Thanks for the look, but nope. I guess it is because there's just one alternation, not two. is an expanded5-cube honeycomb, so geometrically identical to the 5-cubic honeycomb and so its alternation also 5-demicube honeycomb, but a lower symmetry with alternated colors on the 5-demicube facets. This pattern is true for 5D and up, but a bit different for 4D, like the Alternated cubic honeycomb because D~3=A~3. Tom Ruen (talk) 03:38, 3 July 2012 (UTC)Reply
Update: I wasn't quite right - the expanded alternation is only isomorphic for D~3, but has more n-demicube colorings for higher dimensions. Tom Ruen (talk) 00:23, 4 July 2012 (UTC)Reply
