Possible facets here are the 20 triangles and 12 pentagons of the comodore itself together with the 6 internal decagons.
The general naming code here is accordingly `id-#{3}-#{5}-#{10}`.
This gives rise for exactly 7 edge-facetings with `n`-gonal axial rotation symmetries, provided `n > 2`.
In fact, 3 have full icosahedral symmetry, 2 have 5-fold pyramidal symmetry, and 2 have 3-fold pyramidal symmetry.

Possible facets here are the 12 pentagrams and 20 triangles of the comodore itself together with the 6 internal decagrams.
The general naming code here is accordingly `gid-#{5/2}-#{3}-#{10/3}`.
This gives rise for exactly 7 edge-facetings with `n`-gonal axial rotation symmetries, provided `n > 2`.
In fact, 3 have full icosahedral symmetry, 2 have 5-fold pyramidal symmetry, and 2 have 3-fold pyramidal symmetry.
