Decahedron

In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra, and none are regular, so this name does not identify a specific type of polyhedron except for the number of faces. Some decahedra have regular faces: * Octagonal prism (uniform 8-prism) * Square antiprism (uniform 4-antiprism) * Square cupola (Johnson solid 4) * Pentagonal bipyramid (Johnson solid 13, 5-bipyramid) * Augmented pentagonal prism (Johnson solid 52) The decahedra with irregular faces include:
