Abstract

Triangle presentations are combinatorial structures on finite projective geometries which characterize groups acting simply transitively on the vertices of a locally finite building of type . From a type triangle presentation on a geometry of order , we construct a fiber functor on the diagrammatic monoidal category over any field with characteristic such that . When is algebraically closed and odd, this gives new fiber functors on the category of tilting modules for .
