Basically, you take the val of k*N-edo, get the primes with mappings divisible by k (integer steps of N-edo), and for those that don't, find some power, product, or quotient that does. For the 2*N subgroup you'll usually square the first prime mapped to an odd number of 2*N-edo steps and multiply the prime by any other prime mapped to an odd number of steps of 2*N-edo.
