In geometry, a hexecontahedron (or hexacontahedron [1]) is a polyhedron with 60 faces. There are many symmetric forms, and the ones with highest symmetry have icosahedral symmetry:
Four Catalan solids, convex:
- Pentakis dodecahedron - isosceles triangles
- Deltoidal hexecontahedron - kites
- Pentagonal hexecontahedron - pentagons
- Triakis icosahedron - isosceles triangles
Concave
- Rhombic hexecontahedron - rhombi
