You may want to try Algorithm::Combinatorics

I use Algorithm::Combinatorics all the time, but you have to work out which generator, or combination of generators to use for each particular problem, and this one is eluding me.

Also, I suspect that the sequence I need is a subset of one of the classical sequences (combs/perms/variations/partitions), and I would then need to filter the generated sequence, which can be grossly inefficient; so it may be better to program an algorithm that generates the sequence directly?
