|Square truncated trapezohedron|
Johnson solid dual
|Symmetry group||D4d, [2+,8], (2*4)|
|Dual polyhedron||Gyroelongated square dipyramid|
The vertices exist as 4 squares in four parallel planes, with alternating orientation in the middle creating the pentagons.
A truncated trapezohedron has all valence-3 vertices. This means that the dual polyhedrona gyroelongated square dipyramid has all triangular faces.
