This reminded me of how cool the Petersen graph is; a 6-post 🧵.
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.

The Canada/Bosnia World Cup game, the USA/Canada ODI cricket match, and the RBC Canadian Open are all happening simultaneously. You’d think they’d have a little more foresight about this.
Her first non-abelian group! 😍
Please feel free to reply with resources and materials that you know of that aren’t in this thread!
Puzzle for #MathSky: what’s the knot type of this piece of artwork that is on display at the Denver airport?
Fun activity: I provided the blank squares and the blue and inner red arrows, and she filled everything in and figured out the outer arrows and the node labels.
Personally, I would have used r²f and r³f, her choice works too!
First figs of the year from my orchard, and they’re HUGE!
My 7-year-old made her first Cayley graph and Cayley table today! And she LOVED it! At 9pm, she was too excited to go to sleep…”but I just want to do more algebra!” 🥰 #MathSky #VisualAlgebra
My proof of the Riemann Hypothesis is 95% done.
The remaining 5% is just showing that all of the non-trivial zeros have real part 1/2, and then typing it up.
