OEIS Sequences

Prime factorization representation of Stern polynomials: a(0) = 1, a(1) = 2, a(2n) = A003961(a(n)), a(2n+1) = a(n)*a(n+1). A260443

a(n) = n·A276086(n). A324580

Odd bisection of A260443 (the even terms): a(n) = A260443((2·n)+1). A277324

Numbers whose prime factors span an initial interval of prime numbers and whose sequence of prime multiplicities is a palindrome. A317087

Multiplicative encoding of Pascal triangle: Product p(i+1)^C(n,i). A7188

a(n) = 1·2*3 + 4·5*6 + 7·8*9 + 10·11·12 + 13·14·15 + 16·17·18 + ... + (up to n). A319014

Triangle of labeled mobiles (circular rooted trees) with n nodes and k leaves. A55349

Triangle read by rows: T(n,k) = T(n-1,k-1)*T(n,k-1) and T(n,1) = prime(n). A66117

a(n) = n⁴ - n³. A85537

a(n) = ∏_{d∣n, d>1} A000040(A297113(d)), where A000040(n) gives the n-th prime, and A297113(n) = the excess of n plus the index of the largest dividing prime (A046660 + A061395). A332461
