The rectified truncated cube is a polyhedron, constructed as a rectified truncated cube. It has 38 faces: 8 equilateral triangles, 24 isosceles triangles, and 6 octagons.

Topologically, the triangles corresponding to the cube's vertices are always equilateral, although the octagons, while having equal edge lengths, do not have the same edge lengths with the equilateral triangles, having different but alternating angles, causing the other triangles to be isosceles instead.

The rectified truncated cube can be seen in sequence of rectification and truncation operations from the cube. Further truncation, and alternation operations creates two more polyhedra:
