Acronym etoh Name elongated tetrahedral-octahedral honeycomb,elongated alternated cubic honeycomb ` © ©   ©` Confer related CRF honeycombs: gyeditoh   5Y4-4T-6P3-tri-0 Externallinks

Combining each tet with its adjacent trip into an etripy would result in gyeditoh. – If conversely all octs would be dissected by parallel planes into pairs of squippies, this honeycomb would become 5Y4-4T-6P3-tri-0.
