In February 2022, Don Knuth found a cool graph which contains all 4-vertex graphs as subgraphs. Furthermore, they can be visited in revolving-door Gray code order.
He reported about it in exercise 291 in pre-fasicle 7a, and asked if someone could make an animated video of it. This is my attempt at it.
Any remarks or suggestions for improvement are welcome.
