Duopyramid

In geometry of 4 dimensions or higher, a double pyramid, duopyramid, or fusil is a polytope constructed by 2 orthogonal polytopes with edges connecting all pairs of vertices between the two. The term fusil is used by Norman Johnson as a rhombic-shape.[1] The term duopyramid was used by George Olshevsky, as the dual of a duoprism.[2]
