Net of a dextro form

In geometry, a pentagonal icositetrahedron or pentagonal icosikaitetrahedron is a Catalan solid which is the dual of the snub cube. In crystallography it is also called a gyroid.

It has two distinct forms, which are mirror images (or "enantiomorphs") of each other. They are termed dextro and laevo forms.
