Quadratic triangulations for dyadic matroid base polytopes

Let MM be a dyadic matroid, meaning a matroid representable over the dyadic partial field. Let P(M)P(M) be its matroid base polytope. Dyadic matroid triangulation conjecture. The matroid base polytope P(M)P(M) has a quadratic triangulation. The source presents this as a proposed problem motivated by observed connections with representability theory; it also notes that the Fano matroid does not have a quadratic triangulation.
