Ditrigonal prism

The ditrigonal prism or dittip is a prism based on the ditrigon. As such it is a semi-uniform polyhedron with 2 ditrigons nd 2 sets of 3 rectangles as faces.

A ditrigonal prism with height 1, and base edges of lengths 1 and $$\frac{\sqrt5-1}{2}$$ occurs as the vertex figure of the rectified small ditrigonary hexacosihecatonicosachoron. Prisms of nonconvex ditrigons occur as the vertex figures of the rectified great ditrigonary hexacosihecatonicosachoron and rectified ditrigonary dishecatonicosachoron.

The general ditrigonal prism can be alternated into a triangular gyroprism.
