Primeval numbers: numbers that set a record for the number of distinct primes that can be obtained by permuting some subset of their digits. A72857

a(n) = (2·n²)^-1*∑_d∣n (-1)^n+d*moebius(n/d)*binomial(2·d,d). A131868

Numbers with exactly six distinct base-10 digits. A220076

A variant of primeval numbers A072857 where primes are counted with repetition as in A075053, not as in A039993. A239196

Values of n where number of permutations of digits a(n) that are prime increases. A46891

Semiprimes which have one or more occurrences of exactly six different digits. A235694

Number of anagrams of a(n) that are prime increases. A46888

a(1) = 1; for n > 1, a(n) is the smallest positive integer that has not yet appeared which contains all the distinct digits of the sum of all previous terms a(1)..a(n-1). A368347
