The **quasitruncated great stellated dodecahedron**, or **quit gissid**, also called the **great stellated truncated dodecahedron**, is a uniform polyhedron. It consists of 20 triangles and 12 decagrams. Each vertex joins one triangle and two decagrams. As the name suggests, it can be obtained by quasitruncation of the great stellated dodecahedron.

## Vertex coordinates
