I about went crazy trying to find the last one 😂 ... you have 74 marked as prime. Also thanks for putting the evens in the same column, I didn't need to scour through those rows.

I hate that 91 is a prime number. 7 and 13? What kind of factors even are those??

It creates the neat trivia that the last 2-digit number ending in 1 that is prime is 71, since 81 is 9 squared.

You do mean you hate that 91 is not a prime number, right? Otherwise I'm very confused 😅

brings to mind this https://www.youtube.com/watch?v=S75VTAGKQpk John Conway proves that 91 is the smallest number which looks prime but isn't. 2, 3, 5 and 11 all have easy instant divisibility tests, and the squares are all famous, so the smallest must therefore be 7*13 = 91

Meh, I wouldn’t worry. QM probably felt that going to 100 was a bit much.
