OEIS Sequences

Form a triangle with the numbers [0..n] on the base, where each number is the sum of the two below; a(n) is the number of different possible values for the apex. A66411

a(n) = prime(n) * prime(2·n-1). A219603

a(n) = ∑_k=0..n-3 T(n,k) * T(n,k+3), with T given by A026769. A27242

a(1) = 1; for n > 1, a(n) = smallest distinct positive integer such that gcd(a(n),a(n-k)) = 1, where k is each divisor of a(n) and n - k >= 1. A347179

10000n+1, 10000n+3, 10000n+7, 10000n+9 are all primes. A64963
