Actually, if you have rows of squares that are offset
from one another, then you could have squares that
share (at least part of) an edge with six other squares.

If you have triangles in rows
that are offset from one another so the vertices in one
row don't touch the vertices in the next,

Each triangle shares a full edge with two other

edge with two triangles in the row above.
