Sims conjecture
In mathematics, the Sims conjecture is a result in group theory, originally proposed by Charles Sims. He conjectured that if is a primitive permutation group on a finite set and denotes the stabilizer of the point in, then there exists an integer-valued function such that for the length of any orbit of in the set.
The conjecture was proven by Peter Cameron, Cheryl Praeger, Jan Saxl, and Gary Seitz using the classification of finite simple groups, in particular the fact that only finitely many isomorphism types of sporadic groups exist. A consequence of their proof is that there exist only finitely many connected distance-transitive graphs having degree greater than 2.
