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
