OEIS Sequences

Least positive integer multiples of angle·such that their direction cosines form a unit vector: ∑_k>0 cos(a(k)*x)² = 1, where a(1)=1 and x=2. A80137

Exponential convolution of Catalan numbers and factorial numbers. A277176

a(n) = ∑_{k = 0..floor(n/2)} floor(C(n-k,k)/(k+1)). A95719

E.g.f.: exp( Integral exp(x²) dx ). A279840

Number of ways to choose a strict rooted partition of each part in a strict rooted partition of n. A301754

a(n) = ∑_k=1..n σ(n·k). A372710

Least k such that k·6ⁿ-1 , k·6ⁿ+1, and 2·k*6ⁿ-1 are prime; that is, twin primes and a Sophie Germain prime. A212481

50-gonal numbers: a(n) = 48·n*(n-1)/2 + n. A261343
