About the Cascadia Combinatorial Feast

The Cascadia Combinatorial Feast (formerly known as the Combinatorial Potlatch) is an annual, floating, one-day conference. It has been held for many years at various locations around Puget Sound and southern British Columbia, and is an opportunity for combinatorialists in the region to gather informally for a day of invited talks and conversation. While most who attend work in, or near, the Puget Sound basin, all are welcome. Typically there are three talks given by speakers who are visiting or new to the area, along with breaks for coffee and lunch. Many participants remain for dinner at a local restaurant or pub.

In 2020, we decided to change the name of the conference. The original name, Potlatch, referred to a ceremonial feast among certain First Nations of the northwest Pacific coast. You can read more about Potlatches here.

The Fall 2025 conference is being hosted by the Department of Mathematics at Simon Fraser University at their downtown campus in Vancouver, BC on Saturday, November 22, 2025.

More information, including a history and links to previous conferences, is at the Cascadia Combinatorial Feast Home Page.
