OEIS Sequences

Sin(n) decreases monotonically to -1. A46964

a(n) = A348507(A276086(n)), where A348507(n) = A003959(n) - n, A003959 is multiplicative with a(p^e) = (p+1)^e, and A276086 gives the prime product form of primorial base expansion of n. A348950

Number of primitive Pythagorean-like triples a²+b²=c²+k for k=-5 with 0<c<=10ⁿ. A121087

a(1) = 1, and for each n >=2, a(n) is the smallest number such that 1/cos(a(n)) < 1/cos(k) for all k < n, so that 1/cos(a(1)) > 1/cos(a(2)) > ... > 1/cos(a(n)) > ... A172448

a(n) = n! * ∑_k=1..n (-1)^n-k * Stirling1(n,k) * H(k), where H(k) is the k-th harmonic number. A354685

a(0)=1; a(n) is the smallest integer > a(n-1) such that sin(a(n)) is closer to an integer (here 0 or -1) than sin(a(n-1)). A79037

a(n) = ∑_k=1..n 2^nonprime(k). A176496

a(n) = 2·n³ - 4·n² + 6·n - 2 (n>=1). A304159

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n+1-k), where k = [ (n+1)/2 ], s = (odd natural numbers), t = A000201 (lower Wythoff sequence). A24599
