Some #trymathslive because I couldn't quite see how it should work
Not finished, and very much not in the spirit of https://ncatlab.org/nlab/show/fully%20formal%20ETCS#the_theory_of_elementary_toposes but ultimately equivalent

I should have tagged this #trymathslive, like @DavidKButler does on BSky.
This little thread is because I want to add another feature to a very back-burner paper with a coauthor in functional or global analysis or something involving possibly nasty infinite-dimensional topological vector spaces.
But you have to actually know what you should prove first, and no sources I found online ever discussed this stuff in the way I wanted, let alone gave examples that test the boundaries.
My interlocutor elsewhere was taking his own approach, which is fine, but it didn't match what I was doing. I think we'll get there in the end, re: the nLab page.

Now let's return to the 60 available points for wins. My team is already taken 4 of them.
That's 56 left, the other five teams have to split those. Average is 11 per team, but you win those sets of 4. How about one team with eight points and four teams with 12 points?
Aha, then if no other team got any bonus points anywhere, my team wins!
It's a good morning for some #ProblemSolving !
Here's today's Q from the November Calendar.
What do you notice? What would your Ss notice?
I'm going to #TryMathLive #TryMathsLive (thanks to @davidkbutler.bsky.social for this framing)
I am going to #TryMathsLive with this problem from @dhabecker.
