OEIS Sequences

a(n) = 7·binomial(8·n+7,n)/(8·n+7). A234466

Molien series for 3-D group X1. A37240

a(n) = (n-1)*n*(n+1)*(n+2)*(2·n+1)/40. A112851

Fermat coefficients. A971

a(1) = 1, a(2) = 2; a(n) = lcm(n, a(n-2)), a(n+1) = lcm((n+1), a(n-3)) and so on until a(2n-1) = lcm(2n-1, a(1)). Then a(2n) = lcm(2n, a(2n-2)) and so on. A109849

Binomial(prime(n),s)/prime(n) where s is the sum of the decimal digits of n. A176266

a(1) = 1, a(2) = 2, next terms up to a(2n-1) are obtained by multiplying previous terms a(n-1) by n+1, a(n-2) by n+2 etc. a(2) by (2n-2) and a(1) by 2n-1. On similar lines a(2n) = 2n·a(2n-2), a(2n+1) = (2n+1)*a(2n-1) and so on. A109844

Magic sums of 3 X 3 semimagic squares composed of squares of primes. A269344

a(0) = 1; a(n) = ∑_{k=0..floor((n-1)/7)} a(7·k) * a(n-1-7·k). A386396
