Hecke-Farey coordinates for Bring's curve that gives Bring's surface

Doha Kattan, David Singerman

The modular group $Γ$ (which is the Hecke group $H_{3}$ ) can be used to study triangular maps. Here we use the Hecke group $H_{4}$ to study the regular map that underlies Bring's surfa…

Using Hoare's Theorem to find the signature of a subgroup of an NEC group

David Singerman

We explain how to use Hoare's Theorem to find the signature of a subgroup of an NEC group. We give several examples.
