First figs of the year from my orchard, and theyâre HUGE!
This reminded me of how cool the Petersen graph is; a 6-post đ§ľ.
First, what is it? The vertices are labeled by the 2-element subsets of {1,...,5}, and there is an edge between two vertices if the subsets are disjoint.
This gives S5 in its automorphism group; in fact that's all there is.

Her first non-abelian group! đ
Please feel free to reply with resources and materials that you know of that arenât in this thread!

The Canada/Bosnia World Cup game, the USA/Canada ODI cricket match, and the RBC Canadian Open are all happening simultaneously. Youâd think theyâd have a little more foresight about this.
