Gyroelongated square bipyramid
Gyroelongated square bipyramid
Type Johnson
J16 - J17 - J18
Faces 2.8 triangles
Edges 24
Vertices 10
Vertex configuration 2(34)
8(35)
Symmetry group D4d
Dual Square truncated trapezohedron
Properties convex, deltahedron

In geometry, the gyroelongated square bipyramid is one of the Johnson solids (J17). As the name suggests, it can be constructed by gyroelongating an octahedron by inserting a square antiprism between its congruent halves. It is a deltahedron.

The 92 Johnson solids were named and described by Norman Johnson in 1966.
