In mathematics, a permutation is the order of a set of numbers. In anime terms, one permutation of Haruhi would be watching all 14 episodes in the order that they aired. But what if you’re a Haruhi superfan and watching the season once isn’t enough for you? In that case, you might be interested in a superpermutation, or all of the possible permutations of a set strung together. Think of it as the ultimate Haruhi marathon.
THINK OF IT AS THE ULTIMATE ‘HARUHI’ MARATHON
The branch of math that deals with permutations and superpermutations is called combinatorics. It doesn’t require years of study to be good at it, either. “It’s more accessible to amateur and casual mathematicians,” Houston says.
The poster’s anonymity doesn’t invalidate the solution for the mathematicians. “What’s beautiful about mathematics is that it’s a proof that starts with your hypothesis and leads to your conclusion,” Jay Pantone, a mathematician at Marquette University says. “You have to convince a skeptical reader that you’re correct. That doesn’t rely on your identity being known.”
