The ditrigonal pyramid, or ditpy, is a pyramid based on a ditrigon. It has 1 ditrigon as a base and 3+3 isosceles triangles as sides.
In vertex figures[edit | edit source]
Ditrigonal pyramids appear as vertex figures of the truncated small ditrigonary hexacosihecatonicosachoron and small ditrigonary icosidodecahedral prism.
