Discriminants with exactly 1 associated cyclic cubic field. A343022

If F is the Fermat point of a triangle ABC with A < B < C < 2*π/3, where AB, BC, CA, FA, FB and FC are all positive integers, then, this sequence gives the sum FA + FB + FC when gcd(a, b, c) = A351477(n). A351476

a(n) = (p1 + p2)/36 such that p1 >= 5 and p2 = p1 + 2 are twin primes and p1 + p2 is a k-th power with k > 1. A330978
