Completeness conjecture for QED Galois conjugates. Although this list follows from a three-loop result, it is conjectured to be complete to all loop orders.

Let $G$ be a primitive log-divergent $\phi^4$ graph with loop number $h_G$ and $c_2(G)=-z_3$, and let $\delta_m$ be the derivation with respect to the modified parity basis in the…
