A hexadecahedron (or hexakaidecahedron) is a polyhedron with 16 faces. No hexadecahedron is regular ; hence, the name is ambiguous. There are numerous topologically distinct forms of a hexadecahedron, for example the pentadecagonal pyramid , tetradecagonal prism and heptagonal antiprism .
A hexahedron (pl.: hexahedra or hexahedrons) or sexahedron (pl.: sexahedra or sexahedrons) is any polyhedron with six faces.A cube, for example, is a regular hexahedron with all its faces square, and three squares around each vertex.
The bisymmetric hendecahedron contains 11 faces and can be arranged in 3D without gaps. A hendecahedron (or undecahedron) is a polyhedron with 11 faces.There are many topologically distinct forms of a hendecahedron, for example the decagonal pyramid, and enneagonal prism.

In geometry, a polyhedron is a solid in three dimensions with flat faces and straight edges. Every edge has exactly two faces, and every vertex is surrounded by alternating faces and edges.

The regular hexadecagon has Dih 16 symmetry, order 32. There are 4 dihedral subgroups: Dih 8, Dih 4, Dih 2, and Dih 1, and 5 cyclic subgroups: Z 16, Z 8, Z 4, Z 2, and Z 1, the last implying no symmetry.
In geometry, a decahedron is a polyhedron with ten faces.There are 32300 topologically distinct decahedra, [1] [2] and none are regular, so this name does not identify a specific type of polyhedron except for the number of faces.
