Order-4 icositetrachoric tetracomb

The order-4 icositetrachoric tetracomb, or sicot, is a paracompact regular tiling of 4D hyperbolic space. It is paracompact because it has infinite Euclidean vertex figures, with all vertices as ideal points at infinity. 4 icositetrachora meet at each face, and infinitely many meet at each vertex in a cubic honeycomb arrangement.
