CMap::Dart_handle CGAL::make_combinatorial_hexahedron | ( | CMap & | cm) |  |

Creates a combinatorial hexahedron (six combinatorial quadrangles linked together by \( \beta_2\)), and adds it in `cm`.

Returns a handle on one dart of this combinatorial hexahedron.

Precondition
  `CMap::dimension` \(\geq\) 2.
