Resumen:
We re-examine previously found cosmological solutions to eleven-dimensional
supergravity in the light of the E10-approach to M-theory. We focus on the solutions with
non zero electric field determined by geometric configurations (nm, g3), n <10. We show
that these solutions are associated with rank g regular subalgebras of E10, the Dynkin
diagrams of which are the (line) incidence diagrams of the geometric configurations. Our
analysis provides as a byproduct an interesting class of rank-10 Coxeter subgroups of the
Weyl group of E10.
