Great stellated 120-cell

Great stellated 120-cell

In geometry, the great stellated 120-cell is a star polychoron with Schläfli symbol {5/2,3,5}. It is one of 10 regular Schläfli-Hess polychora.

It is one of four "regular star polychora" discovered by Ludwig Schläfli. It is named by John Horton Conway, extending the naming system by Arthur Cayley for the Kepler-Poinsot solids.

It has the same edge arrangement as the grand 600-cell, icosahedral 120-cell, and the same face arrangement as the grand stellated 120-cell.
