What is a 400 sided polyhedron called?

A 400-sided polyhedron is called a "tetrahectahedron," though this term is not commonly used. In general, polyhedra are named based on the number of their faces, and for a 400-sided polyhedron, the prefix "hecta-" denotes its relation to the number 100. However, practical applications and discussions usually involve simpler polyhedra with fewer faces.
