I had an interesting thing happen in my last session of Dungeons and Dragons 5th edition. My players are in a dragon heavy adventure. A player tried to do a perception check to detect the scent of lilacs. Normally whenever a character wants to do a perception check I just tell them to go for it,...

The Cohen-Lenstra paper says the probability that the odd part of a class group being cyclic is close to 0.98. So I was thinking: can we find any conditions on a finite abelian group so that it cannot be a class group of any number field?

I was surprised to read that Redstone used 75% ethyl alcohol as a fuel.
