Coxeter states that every parallel-sided 2"m"-gon can be divided into m(m-1)/2 rhombs. For the "regular hexadecagon", "m"=8, and it can be divided into 28: 4 squares and 3 sets of 8 rhombs. This decomposition is based on a Petrie polygon projection of a 8-cube, with 28 of 1792 faces. The list A006245 enumerates the number of solutions as 1232944, including up to 16-fold rotations and chiral forms in reflection.
