Additional Information and References:

“Ten faces, not turned of twelve but twenty-four, because each star-pentagon has another one crossing it, but not in the symmetrical fashion. They’re at a peculiar angle to each other and the corners of the pairs of pentagrams do not form a regular decagon.” H.S.M. Coxeter. Dec. 23, 1999
