Title: The 600-cell as a Cayley graph

Abstract:

I will discuss some of the things we can learn about the 600-cell by viewing it as a Cayley graph for the group SL(2,5) (once I've discussed the basic properties of this group).

Title: Partial progress on enumerating K5 descendants

Abstract:

We call a particular operation on a graph which converts one triangle into two triangles a double triangle expansion, and call all those graphs which can be obtained from repeated double triangle expansions of a fixed graph the double triangle descendants of the graph.
