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 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.

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.
Being the dual of an Archimedean solid, the rhombic triacontahedron is face-transitive, meaning the symmetry group of the solid acts transitively on the set of faces. This means that for any two faces, A and B , there is a rotation or reflection of the solid that leaves it occupying the same region of space while moving face A to face B .
