In the
geometry of
hyperbolic 3-space, the
order-7 dodecahedral honeycomb is a regular space-filling
tessellation (or
honeycomb).
Geometry
With Schläfli symbol, it has seven dodecahedra around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many dodecahedra existing around each vertex in an order-7 triangular tiling vertex arrangement.
