OEIS Sequences

Number of partitions of n that sorted in increasing order do not contain a part k in position k. A238394

Number of ordered pairs (x, y) with gcd(x, y) = 1 and 1 <= {x, y} <= 2ⁿ. A342632

G.f. satisfies: A(x) = exp( ∑_n>=1 xⁿ/n * ∏_k>=1 (1 + x^n·k*A(xⁿ)^k) ). A219232

Number of 3-element subsets of {1,...,n} whose sum has more than 3 divisors. A241564

Underline the central digit of all terms: the underlined digits reconstruct the starting sequence. This is also true if one translates the sequence in French and underlines the central letter of each word: the underlined letters spell the (French) sequence again. This is the lexicographically earliest sequence where repeated terms are admitted. A319718

a(n) = A083964(n)/(2n-1). A83965

a(n) = 324n - 1. A158306

Numbers of the form p² * q where p and q are primes with p < q < p². A355446

Positive numbers k such that k and 3·k are anagrams in base 9 (written in base 9). A23080

Number of partitions in parts not of the form 9k, 9k+1 or 9k-1. Also number of partitions with no part of size 1 and differences between parts at distance 3 are greater than 1. A35940
