Appears in sequences

• Numbers m such that m = prime(d_1) * prime(d_2) * ... * prime(d_k), where d_1 d_2 ... d_k is the decimal expansion of m.at n=3A097227
• Let prime(0) = 1 and f(n) = product prime(d), where d ranges over all the decimal digits of n. The sequence gives numbers n such that f(n) == 0 (mod n).at n=7A113735
• For a given n, the nonzero digits of n are the prime indices for the factorization of n.at n=4A290675
• Numbers whose set of decimal digits coincides with the set of the indices of their prime factors.at n=8A318298
• Numbers n such that n = prime(d_1) * prime(d_2) * ... * prime(d_k), where n is a concatenation of d_1, d_2, ..., d_k.at n=7A329711
