Query: Characterising inflations of monotone grid classes of permutations   We characterise those permutation classes whose simple permutations are
monotone griddable. This characterisation is obtained by identifying a set of
nine substructures, at least one of which must occur in any simple permutation
containing a long sum of 21s.
