Decompose the multiplicative group of integers modulo N as a product of cyclic groups C_k₁ x C_k₂ x ... x C_{k_m}, where k_i divides k_j for i < j, then a(n) is the smallest N such that the product contains a copy of C_2n. A302099

a(n) is the smallest k such that the p-rank of (Z/kZ)* is 2, where p = prime(n) and (Z/kZ)* is the multiplicative group of integers modulo n. A307434
