• To each (lower adjusted partial) flag of length k in an n-dimensional vector space over GF(q) we assign an injective mapping ψ of {1,....,k} into {1,....,n} in such a way that evactly q^<l(ψ)> of the flags map into a given mapping ψ, where l(ψ) is the generalized "inversion number". The construction may also be regarded as an order-preserving mapping from the lattice of flags into the lattice of nests.
