Possible facets here are the 12 pentagrams of the comodore itself together with the 20 internal triangles.
The general naming code here is accordingly `sissid-#{5/2}-#{3}`.
This gives rise for exactly 13 edge-facetings with `n`-gonal axial rotation symmetries, where `n > 2`.
In fact, 2 have full icosahedral symmetry, 5 have 5-fold pyramidal symmetry, 1 has 5-fold antiprismatic symmetry,
3 have 3-fold pyramidal symmetry, and 2 have 3-fold antiprismatic symmetry.
