a(n) is the smallest number such that there are exactly n numbers k (including a(n) itself) such that U(k) is isomorphic to U(a(n)) (or 0 if no such number exists). Here U(k) is the multiplicative group of integers modulo k. A303712

a(n) = ∏_{k in GB(2·n)} k, where GB(n) is the set of primes which are Goldbach-associated with n. A338777
