This category consists of compounds of tets and compounds of cubes that have yet to be counted. All of these are orientable. Sis has tetrahedral symmetry, the others have cubic symmetry.

**C29. Rah** - (RAH) rhombihexahedron. Faces are 6 squares and 12 rhombic squares. It is a compound of 3 cubes. It has 24 vertices and its verf is a triangle.

**C30. Risdoh** - (RISS doe) rhombisnub dishexahedron. Faces are 12 squares (paired up) and 24 snub squares. It is a compound of 6 cubes and is flexible. It has 48 vertices and its verf is a triangle.

**C31. Snu** - (SNU) snubahedron. Faces are 24 snub triangles. It is a compound of 6 tets and has cubic symmetry. It has 24 vertices and its verf is a triangle.

**C32. Sis** - (SIS) small snubahedron. Faces are 24 snub triangles. It is a compound of 6 tets and has tet symmetry, it is topologically the same as snu, but with a different symmetry. It has 24 vertices and its verf is a triangle. This one is flexible.

**C33. Dis** - (DISS) Disnubahedron. Faces are 48 snub triangles. It is a compound of 12 tets and is flexible. It has 48 vertices. Its verf is a triangle.
