Title: Sub-maximal symmetry and integrability

Abstract:
I will discuss the results on the gap problem in the symmetry dimensions of parabolic geometries (joint with D.The). Then I will tell about further progress for more general geometries (joint with V.Matveev, H.Winther, D.The), and relation to integrability in finite-type systems. I finish with speculations about the problem in the infinite-type case and infinite-dimensional Lie pseudogroups.
