OEIS Sequences

Odd composites k, not powers of primes, such that for all their nontrivial unitary divisors d it holds that A347381(d) > A347381(k). A347383

Sequence of pairwise relatively prime numbers of class P₄ (see comment in A275246). A275248

a(n) = (12·n+1)*(12·n+11). A1538

After the initial 1, numbers k such that A347381 obtains its minimum value at k, of all the divisors d of k larger than one, where A347381 is the distance from n to the nearest common ancestor of n and σ(n) in the Doudna-tree (A005940). A374218
