Coordinates
As a regular honeycomb, {3,3,4,3}, it has no lower dimensional analogues, but as an alternated form (the demitesseractic honeycomb, h{4,3,3,4}) it is related to the alternated cubic honeycomb.
Vertices can be placed at all integer coordinates (i,j,k,l), such that the sum of the coordinates is even.
