Cantellation (geometry)

Cantellation is a geometric operation that involves the modification of a polyhedron or polytope by truncating its vertices. When you cantell a polyhedron, you effectively "cut off" its vertices, creating new faces that replace the original vertices with additional edges, typically forming a structure that combines aspects of the original shape and its modified version. The result of cantellation can create more complex shapes with additional faces while preserving some of the properties of the original polyhedron.
