Is the classification of space-filling (by identical copies) convex polyhedra in R^3 is known ?
There are only 5 "parallelohedra" - filling by translation. But if relax that property to identical (but not necessary by parallel translation), there are more as Wikipedia suggests. But it is not clear is the list described there is final or not.
To be precise I am asking about honeycombs filling the space by copies of single polyhedron, not several of them, as it happens, for example in famous Weaire–Phelan structure.
