Edge-connected faces are called polykites. Reflections are included separately in the counts. Polykites can have from 1 to 60 faces. %C A340635 These polykites are counted up to the full icosahedral group (order 120) of the deltoidal hexecontahedron. - _Peter Kagey_, Apr 28 2025 %H A340635 Wikipedia, <a href="https://en.wikipedia.org/wiki/Deltoidal_hexecontahedron">Deltoidal Hexecontahedron</a> %Y A340635 Cf.
