Appears in sequences

• a(n) is the constant term in the expansion of (1 + (1+x)*(1+y) + (1+1/x)*(1+1/y) + (1+1/x^2)*(1+1/y^2))^n.at n=6A327994
• Lexicographically earliest infinite sequence of distinct primes such that, for n > 0, 2n | (a(n+1) - a(n)) and, for n > 0, b(n+1) > b(n) where b(n) = (a(n+1) - a(n)) / 2n.at n=40A350392
