OEIS Sequences

Number of 2-trees rooted at an asymmetric end-edge. A63682

Consider trajectory of n under repeated applications of the function f(x) = 'Sum of the prime factors of x (with multiplicity)' (see A029908). Sequence gives composite numbers n that end at a prime m that divides n and m is greater than any m's seen already. A84931

a(n) = numerator of constant λ(n) involved in a recurrence for the Atkin polynomials A_k(j). A145226

Squarefree numbers k such that the sum of the distinct prime factors of k is twice the difference between the largest and the smallest prime factors of k. A324210

a(n) = ∑_k=1..n σ(k)*2^n-k where σ(k) = A000203(k) is the sum of divisors of k. A66767
