# Uniform Adjacency

From Pyxis public wiki

In a Discrete Global Grid, the property of adjacent cells sharing only sides, not vertexes, such that the distances from one cellâ€™s point to those of all its neighbours are equal. Hexagons have uniform adjacency: in a grid, each is adjacent to exactly six others. In contrast, a covering made up of squares has two kinds of adjacency: sharing a side or touching at a vertex.
