| Abstract: | Properties of symmetrical q-extensions of grids are investigated. A criterion is obtained for a set of symmetrical q-extensions of the 2-dimensional grid Λ2 to be finite. This criterion is used to prove, in particular, that the set of all Aut 0(Λ2)-symmetrical q-extensions of the grid Λ2 is finite for any prime q. The list of all Aut 0(Λ2)-symmetrical 3-extensions of the grid Λ2 is obtained. |
