OEIS Sequences

a(n) is the smallest number k larger than a(n-1) such that n·d(k)*sopf(k)=σ(k), where d is the number of divisors (A000005) and sopf the sum of prime factors without repetition (A008472). A134382

T(n,k)=Number of nXk 0..1 arrays with each 1 horizontally or vertically adjacent to 1, 3 or 4 1s. A295551

Coefficients in the expansion of C⁴/B⁵, in Watson's notation of page 118. A160528

a(n) = 11ⁿ + n. A226737

Number of integer partitions of n whose multiplicities have multiplicities that cover an initial interval of positive integers. A325330

a(n) = n⁴+4 = (n²-2·n+2)*(n²+2·n+2) = ((n-1)²+1)*((n+1)²+1). A57781

a(n) = smallest k having at least three prime divisors d such that (d + n) | (k + n). A202158

Rectangular array: (row n) = b**c, where b(h) = h³, c(h) = (n-1+h)³, n>=1, h>=1, and ** = convolution. A213558
