The triangular fissary duoalterprism or trufdap is a nonconvex fissary scaliform polychoron. It consists of 12 parabidiminished ditrigonal icosidodecahedra, 36 pentagonal-pentagrammic wedge blends, and 24 octahedra.
The triangular spinoduoalterprism is one of the two known scaliform polychora with G2+≀S2×2 symmetry, the other being the triangular spinoduoalterprism.
