N2 - The amplituhedron An,k,4 is a geometric object, discovered by ArkaniHamed and Trnka (2013) in the study of scattering amplitudes in quantum field theories. They conjecture that An,k,4 admits a decomposition into tiles, which is based on a certain combinatorial structure. The tiles are images of BCFW positroid cells in the nonnegative Grassmannian Gr ≥k,n that arise from the Britto–Cachazo–Feng–Witten recurrence (2005).
