OEIS Sequences

Decimal encoding of the prime factorization of n: concatenation of prime factors and exponents. A67599

Number of distinct values taken by 4⁴^...⁴ (with n 4's and parentheses inserted in all possible ways). A3019

Numbers with multiplicative digital root value 9. A34056

Numbers with at least 2 distinct digits and whose "rotations" (including the number itself) are multiples of these digits; repeated digits allowed but digit 0 not allowed. A66484

Concatenations of pairs of primes that differ by 100. A103523

Concatenations x||1||x for numbers x. A392225

a(1) = 1; thereafter a(n) is always the smallest integer > a(n-1) not leading to a contradiction, such that the concatenation of any three consecutive digits in the sequence is a prime. A152608

a(1) = 11 by convention; for n > 1, if n = p^a*q^b... then a(n) = concatenate(p,a,q,b,...). A68633
