Abstract: I'll talk about a classical way from the 1960's to derive a presentation for the special linear group over the Gaussian integers by viewing it as a group acting on the Hyperbolic plane. Then I'll talk about my way to find a presentation of the group by viewing it as acting on a variation on the curve complex of a torus. The talk will be interactive and compare and contrast the two methods.
