Abstract
We determine the four-point correlation function and amplitude in planar, maximally supersymmetric Yang-Mills theory to 12 loops. We find that the recently introduced “double-triangle” rule in fact implies the previously described square and pentagon rules; and when applied to 12 loops, it fully determines the 11-loop correlator and fixes all but 3 of the (619,981,403) 12-loop coefficients; these remaining coefficients can be subsequently fixed using the “(single-)triangle” rule. Not only do we confirm the Catalan conjecture for antiprism graphs, but we discover evidence for a greatly generalized Catalan conjecture for the coefficients of all polygon-framed fishnet graphs. We provide all contributions through 12 loops as Supplemental Material to this work.

Many of the on-shell diagrams counted in Table 1 will vanish upon Fermionic integration. However, the number which vanish depends strongly on recursive choices made, but always appear to leave an fraction nonvanishing.

More precisely, we require any two intersecting threads to intersect normally (not tangentially) at a valency-4 vertex, and all threads along the same diagonal direction must lie in parallel.
Put differently, a polygon-framed fishnet is obtained by choosing a set of diagonals [including the diagonals already present] of a -point antiprism and thickening each diagonal into a bunch of threads.
