OEIS Sequences

Sequence is {a(7,n)}, where a(m,n) is defined in sequence A110665. A110672

Values of n such that L(17) and N(17) are both prime, where L(k) = (n²+n+1)*2^2·k + (2·n+1)*2^k + 1, N(k) = (n²+n+1)*2^k + n. A227520

Number of rucksack partitions of n: every consecutive constant subsequence has a different sum. A353864

a(n) = σ(n) * A003961(n), where A003961 shifts the prime factorization of n one step towards larger primes, and σ is the sum of the divisors of n. A341529

a(n) = ∑_d∣3 φ(d)*n^3/d. A54602

15-gonal (or pentadecagonal) numbers: n*(13n-11)/2. A51867

a(0) = 1, a(1) = 19; for n > 1, a(n) = 19·a(n-1) + a(n-2). A243399

Numbers that are not a power of a prime but whose prime indices satisfy (mean) = (median) = (mode), assuming there is a unique mode. A363729

Numbers primitive with respect to having more than one factorization into S-primes. See related sequences for definition. A57950

Root of the upper member A340701 of a pair of adjacent perfect powers, both with exponents > 2. A340703
