from 1 to n in a cycle, so that each is a divisor of the sum of the previous k members? There's a trivial example with n = 3 and k = 2, but I haven't found others.
If my program is correct, there are no others for k=2 for 23 < n < 61. I haven't found any with k=3, but my program isn't sufficiently general to rule them out.
