Suppose that f (x) =x⁴+Ax³+Bx²+Ax+1 Zx. We say that f (x) is monogenic if f (x) is irreducible over Q and \1, , ², ³\ is a basis for the ring of integers of Q (), where f () =0. For each possible Galois group G that can occur in the two cases of A 0 with B=0, and AB 0, we determine all monogenic polynomials f (x) with Galois group G.
