The subdegrees of a transitive permutation group are the orbit lengths of apoint stabilizer. For a finite primitive permutation group which is not cyclicof prime order, the largest subdegree shares a non-trivial common factor witheach non-trivial subdegree. On the other hand it is possible for non-trivialsubdegrees of primitive groups to be coprime, a famous example being the rank 5action of the small Janko group on 266 points which has subdegrees of lengths11 and 12. We prove that, for every finite primitive group, the maximal size ofa set of pairwise coprime non-trivial subdegrees is at most 2.
