The pentagonal orthocupolarotunda is the 32nd Johnson solid. It can be constructed by gluing a pentagonal rotunda and a pentagonal cupola at their decagonal faces.
Coordinates
These coordinates give a pentagonal orthocupolarotunda having edge length 2, with its 5-fold axis of symmetry aligned to the Z-axis:
