The **great pyramidic swirlprism** or **gypasp** is a nonconvex noble scaliform polychoron. It consists of 240 pentagrammic pyramids in 120 coplanar pairs.

It can be formed by blending a great swirlprism with a great faceted hexacosichoron.

Its vertex figure is the dual of the vertex figure of sisp.

## Vertex coordinates[edit | edit source]

Its vertex coordinates are the same as those of the general of its army, the hexacosichoron.
