It results from composing the two enantiomorphs of the compound of six pentagrammic prisms. It has two distinct forms, which are mirror images (or "enantiomorphs") of each other. There are 32 possible point groups, and 22 of these are capable of forming enantiomorphs. Not counting the enantiomorphs, bipyramids, and trapezohedra, there are a total of 13 Catalan solids. This is enantiomorphism, and the mirror images are said to be enantiomorphs of each other. A chiral object and its mirror image are said to be enantiomorphs. In general, an object and its mirror image are called enantiomorphs. They are not necessarily mirror-symmetric; e.g. "GP"(5,3) and "GP"(3,5) are enantiomorphs of each other.
