OEIS Sequences

Numbers obtained by reinterpreting base-2 representation of n in primorial base: a(0) = 0, a(2n) = A276154(a(n)), a(2n+1) = 1 + A276154(a(n)). A276156

a(n) = 4·n² - 7·n + 4. A54567

a(n) = n concatenated with n + 1. A1704

Numbers m such that the Bernoulli number B_m has denominator 42. A51228

Numbers k such that the largest prime factor of k²-1 is 101. A181568

Numbers k for which A003415(k) >= A276086(k), where A003415 is the arithmetic derivative and A276086 is the primorial base exp-function. A351228

a(n) = ∑_k=1..n floor(n/k)². A222548

Concatenation of two or more consecutive positive integers. A35333

Lexicographically earliest sequence containing 3 and all positive integers n such that the prime indices of n - 1 already belong to the sequence. A324703

a(1) = 1; a(n) = max{ 5·a(k) + a(n-k) | 1 <= k <= n/2 } for n > 1. A130667
