A permutation of the integers >= 2 which is constructed by swapping each prime's index difference (from the previous prime) and the prime's power in the factorization of a number. In order the "index difference" to make sense the we consider the factorization to be sorted with respect to the primes but not the powers they are raised to, that is, first comes the smallest prime and each subsequent prime is larger than the previous disregarding their powers. |
