On the Subgroups of the Extended Hecke, Hecke and Picard Groups
Ma. Louise Antonette N. De Las Penas, Ma. Carlota B. Decena, Glenn R. Laigo
In this work, we derive the low index subgroups of the extended Hecke, Hecke and the Picard groups using tools in color symmetry theory. We also present the low index subgroups of…

Ma. Louise N. De Las Penas, Rene P. Felix, Glenn R. Laigo
We present a framework to determine subgroups of tetrahedron groups and tetrahedron Kleinian groups, based on tools in color symmetry theory.
