The {6,6∣5} is a compact regular skew apeirohedron in 3-dimensional hyperbolic space. Its faces are precisely the hexagonal faces of the cyclotruncated icosahedral-dodecahedral honeycomb. It is a self-dual polyhedron, and it also shares a symmetry group with another hyperbolic regular skew apeirohedron: {10,10∣3}.
