Are you kidding? 57 is interesting. From Wikipedia:
57 is semiprime, a Blum integer, and a Leyland number.[3]
The split Lie algebra Eโ 7+ 1 / 2 โ has a 57-dimensional Heisenberg algebra as its nilradical, and the smallest possible homogeneous space for E8 is also 57-dimensional.
Although fifty-seven is not prime, it is jokingly known as the Grothendieck prime after a legend in which the mathematician Alexander Grothendieck gave it as an example of a prime number, not realizing it was divisible by three. The same error was made by another famous mathematician, Hermann Weyl, in a published article.
Well, certainly that was more information than I knew about it, thanks!
