If you're unfamiliar with the idea, there's a good piece online from Quanta Magazine talking with Sloane about the website.
About a year and half ago, I started working on a chapter for my now-cancelled Kickstarter book called, "Babyface, Heels and Graph Theory". One of things I wondered was how many "traditional" pro-wrestling matches were possible were possible with
I go into greater detail in the PDF (I put the work-in-progress chapter up for free via PayHip yesterday), but when I asked a math professor friend for help, he explained that the sum of the partitions we were calculating was actually the same as a OEIS sequence #A023998.
If you had 8 wrestlers (4 faces, 4 heels) and followed the conditions that I outline (book them in matches where each team is only compromised of babyfaces or heels and everyone wrestles once in either a singles, tag or multi-man tag match), you find there's 131 different "cards" you can put together (before you start accounting for the order on the card). By the time you have a dozen wrestlers, there's well over twenty thousand. And then things start growing even more rapidly.
