Acronym stippy Name stellated-pentagonal prismatic pyramid,vertex pyramid of the rectified grand hexacosachoron Circumradius sqrt[5-2 sqrt(5)] = 0.726543 Confer general pyramids: pt || n/d-p   general polytopal classes: segmentochora

As abstract polytope stippy is isomorphic to pippy, thereby replacing pentagrams by pentagons resp. replacing stip by pip and stappy by peppy.
