Gyroelongated triangular bicupola

The gyroelongated triangular bicupola, or gyetibcu, is one of the 92 Johnson solids (J44). It consists of 2+3+3+3+3+3+3 triangles and 6 squares. It can be constructed by attaching triangular cupolas -to the bases of the hexagonal antiprism.

It is one of the five Johnson solids to be chiral.
