In geometry, John Horton Conway defines architectonic and catoptric tessellations as the uniform tessellations (or honeycombs) of Euclidean 3-space with prime space groups and their duals, as three-dimensional analogue of the Platonic, Archimedean, and Catalan tiling of the plane.
The cubille is the only Platonic (regular) tessellation of 3-space, and is self-dual.
There are other uniform honeycombs constructed as gyrations or prismatic stacks (and their duals) which are excluded from these categories.
The pairs of architectonic and catoptric tessellations are listed below with their symmetry group.
These tessellations only represent four symmetry space groups, and also all within the cubic crystal system.
