Gyroelongated pentagonal cupolarotunda

The gyroelongated pentagonal cupolarotunda is one of the 92 Johnson solids (J47). It consists of 5+5+5+5+5+5+5 triangles, 5 squares, and 1+1+5 pentagons. It can be constructed by attaching a pentagonal cupola and a pentagonal rotunda to opposite bases of the decagonal antiprism.

It is one of five Johnson solids to be chiral.
