OEIS Sequences

a(1) = 1; a(n) = first odd number greater than a(n-1) such that a(n) + a(i) + 1 is prime for all i=1,2,...,n. A119751

Number of integer partitions of n with sortable prime factors. A326333

Square array A(n,k), n >= 0, k >= 0, read by antidiagonals, where column k is the expansion of exp(∑_j>0 sigma_k(j)*x^j/j) in powers of x. A294946

a(n) is the initial element of the sequence A(n) defined exactly like A119751 but with the additional condition that each of its elements must not be contained in any of the sequences A(k) for k < n. A127256

Beginning with 2, distinct even numbers such that the arithmetic mean of successive pairs of terms gives odd primes in their natural order. {a(n) + a(n+1)}/2 = prime(n+1). A86529
