Possible facets here are the 12 pentagrams, 30 squares, and 12 pentagons of the comodore itself together with the 20 internal hexagons. The general naming code here is accordingly raded-#{5/2}-#{4}-#{5}-#{6}. This gives rise for exactly 33 edge-facetings with n-gonal axial rotation symmetries, where n > 2. In fact, 3 have full icosahedral symmetry, 12 have 5-fold pyramidal symmetry, 2 have 5-fold antiprismatic symmetry, 12 have 3-fold pyramidal symmetry, and 4 have 3fold antiprismatic symmetry.
