The 14 PGD Kaleidoscopic Subgroups

We list here all 14 kaleidoscopic subgroups of *246 that are compatible with the genus-3 translational unit (ooo) for the P, G, and D surfaces. A kaleidoscopic subgroup is one with an orbifold that has a single boundary component and no other symmetry features. There are a total of 131 subgroups of *246 that retain the ooo translational symmetry. A complete list is available here.
