Title: The 600-cell as a Cayley graph
Speaker: Chris Godsil Affiliation: University of Waterloo Room: MC 5479Abstract:
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
Speaker: Karen Yeats Affiliation: University of Waterloo Room: MC 5417Abstract:
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.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
