T = O(n) means that there exists a single constant k such that T < kn for all sufficiently large n. Therefore O(n!^2) is not the the same as O(n!), but for example both 10n!, 10000n!, n! + n^2 (note the plus) are O(n!).

Another way to think about this: suppose you believe that O(n) and O(n^2) are distinct. Now plug in only numbers that are factorials (2, 6, 24, …).

The disambiguation page for Boogaloo is now a bunch of awesome shit like music and dance styles plus an extremist movement…

Fuck you, choose a different name for your whack ass antics.

That is an excellent point…

Seems fake if the claim is that the realtor saw this at a showing, property, etc. You can see a stall divider in the upper left.

This one?
