LOL, from 42:00 on it goes something like this: Professor: How are these group actions different? Student: The one on the right has fixpoints. Professor: Yeah..., but you know, that’s not the real reason. You see, it’s because the left one is free and the other isn’t, because notice: at the pole there is obviously a fixpoint!

@@paul_tee For me somehow the slogan „free is fixpoint-free“ works quite well, so gx = x implies g = 1 for any g, x. Then faithful is „just the other thing“. (But I must confess: due to not working with group actions so much currently I checked again in Wikipedia - just to be sure...)

@@hdbrot "free is fixpoint-free" Not true. An action can be non-free even without any fixed points. That's why the professor said it's not the real reason.

@@YY-wu7et An action can be non-free even if it has no point that is fixed by all group elements. In my earlier comment I meant a fixpoint of a single non-identity element. But I admit that it is the latter what is usually called a fixpoint, so I correct my mnemonic to “free is hereditarily fixpoint-free“ meaning that no action induced by a non-trivial subgroup has any fixpoints.
