• a(n) is the smallest integer m such that n is the least exponent k satisfying sigma(m)^k divides m.at n=13A264155
• Let S = smallest missing positive number, adjoin S, 3*S, 9*S, 27*S, 81*S, ... to the sequence until reaching a term that has S as a substring; reset S to the smallest missing positive number, repeat.at n=46A331631
