a second pair of opposite edges, comprising:
a third edge comprising a single upward tongue, at least one upward flank lying at a distance from the upward tongue and a single upward groove formed between the upward tongue and the upward flank, and
a fourth edge comprising a single downward tongue, at least one downward flank lying at a distance from the downward tongue, and a single downward groove formed between the downward tongue and the downward flank,
wherein a side of the downward tongue facing away from the downward flank is provided with a locking element, and wherein the upward flank is provided with a complementary counter-locking element, said locking element being adapted to cooperate with said counter-locking element of another panel, wherein a level of a highest part of the upward tongue differs from a level of said locking element and/or said counter-locking element,
the third and fourth edges being designed such that locking takes place during coupling of the second panel at a first edge to a second edge of the panel, and wherein the downward tongue of the fourth edge of the second panel will be forced into the upward groove of the third edge of the third panel and the upward tongue of the third panel will be forced into the downward groove of the second panel, by deformation of the third edge and/or the fourth edge, leading to locking of adjacent panels at the third and fourth edges in both the horizontal direction and the vertical direction,
wherein at least a part of a side of the upward tongue facing toward the upward flank is inclined and extends away from the direction of the normal of the upper side or lower side of the core,
wherein at least a part of a side of the downward tongue facing toward the downward flank is inclined and extends away from the direction of the normal of the lower side or upper side of the core, and wherein, in coupled condition of adjacent panels a distance is present between the upward tongue of said panel and the downward flank of an adjacent panel.
2. The panel according to claim 1 , wherein a side of the shoulder facing the core has an inclined orientation for forcing two panels, in an assembled state, toward each other.
3. The panel according to claim 1 , wherein at least a part of an upper side of the upward tongue is planar, and wherein at least a part of an upper side of the downward groove is planar.
4. The panel according to claim 1 , wherein at least a part of an upper side of the upward tongue is curved, and wherein at least a part of an upper side of the downward groove is curved.
5. The panel according to claim 1 , wherein a top structure is arranged on top of the core wherein the top structure comprises a decorative layer and a protective layer arranged on top of said decorative layer.
6. The panel according to claim 1 , wherein at least a part of the lower wall part of the upward groove and at least a part of a lower side of the downward tongue are planar.
7. The panel according to claim 1 , wherein, in coupled condition of adjacent panels, the third edge and the fourth edge do not exert a force onto each other and are free of pretension.
8. The panel according to claim 1 , wherein, in coupled condition of adjacent panels, a pretension is present between the third edge and the fourth edge.
9. The panel according to claim 1 , wherein the co-action between the locking element and the counter-locking element realises a locking in vertical direction.
10. The panel according to claim 1 , wherein the locking element comprises a recess, and that the counter-locking element comprises a bulge, which bulge is adapted to be received in said recess of an adjacent coupled panel for the purpose of realizing a locked coupling.
11. The panel according to claim 1 , wherein the locking element is provided with an inclined abutment surface for abutment with the counter-locking element, and/or the counter-locking element is provided with an inclined abutment surface for abutment with the locking element.
12. The panel according to claim 1 , wherein at least a part of the upward flank adjoining the upper side of the panel is adapted to make contact with at least a part of the downward tongue adjoining the upper side of another panel in an assembled state.
13. The panel according to claim 1 , wherein the upper side of the panel is adapted to engage substantially seamless to the upper side of another panel.
14. The panel according to claim 1 , wherein at least a part of an upper side of the upward tongue runs inclining downward in the direction of the side of the upward tongue facing away from upward flank, and wherein an upper side of the downward groove having an inclining orientation upward in the direction of the side of the downward tongue facing towards to downward flank.
15. The panel according to claim 1 , wherein, in coupled state of two panels, at least one space is present in between a side of the downward tongue facing away from the downward flank, and the upward flank of the third edge.
16. The panel according to claim 1 , wherein a part of the upward flank of the third edge connecting to the core forms a stop surface for at least a part of the side of the downward tongue facing away from the downward flank.
17. The panel according to claim 1 , wherein a part of the upward flank of the third edge connecting to the core is oriented substantially vertically and/or wherein at least a part of the side of the downward tongue facing away from the downward flank is oriented substantially vertically.
18. The panel according to claim 1 , wherein the upward groove is given a form such that this upward groove is adapted for receiving in locked manner at least a part of a downward tongue of an adjacent panel wherein the upward groove is adapted to receive with clamping fit a downward tongue of an adjacent panel and wherein the downward groove is adapted to receive with clamping fit an upward tongue of an adjacent panel.
19. The panel according to claim 1 , wherein at least a part of a side of the upward tongue facing away from the upward flank comprises a first locking element, and wherein the downward flank comprises a second locking element adapted for co-action with a first locking element of a third edge of a third panel.
20. The panel according to claim 19 , wherein the second locking element is positioned at a distance from an upper side of the downward groove and/or wherein the second locking element is positioned at a distance from a lower side of the downward groove.
21. The panel according to claim 19 , wherein the first locking element is positioned at a distance from an upper side of the upward tongue and/or wherein the first locking element is positioned at a distance from a lower side of the upward tongue.
22. The panel according to claim 19 , wherein the first locking element comprises at least one outward bulge, and that the second locking element comprises at least one recess, which outward bulge is adapted to be at least partially received in a recess of an adjacent coupled panel for the purpose of realizing a locked coupling.
23. The panel according to claim 19 , wherein the first locking element is provided with an inclined abutment surface for abutment with the second locking element, and wherein the second locking element is provided with an inclined abutment surface for abutment with the first locking element.
