• Composites that use the same digits as their prime factorization.at n=13A025283
• 1, together with numbers n that are the product of two primes p and q such that the multiset of the digits of n coincides with the multiset of the digits of p and q.at n=6A080718
• Composite numbers having the same digits as their prime factors (with multiplicity), excluding zero digits.at n=10A176670
• Consider a number of k digits n = d_(k)*10^(k-1) + d_(k-1)*10^(k-2) + … + d_(2)*10 + d_(1). Sequence lists the numbers n such that sigma(n) - n = Sum_{i=1..k-1}{phi(Sum_{j=1..i}{d_(k-j+1)*10^(i-j)})} (see example below).at n=9A240900
• Composite numbers having the same digits as their prime factors (with multiplicity), including zero digits.at n=5A280928
• Composite numbers that are anagrams of the concatenation of their prime factors.at n=18A306474
