Integer invariants of an incidence matrix related to Rota's basis conjecture

We compute the spectrum and Smith normal form of the incidence matrix of disjoint transversals, a combinatorial object closely related to the n-dimensional case of Rota's basis conjecture.

The Elementary Divisors of the Incidence Matrices of Skew Lines in PG(3,p)

The elementary divisors of the incidence matrices of lines in $PG(3,p)$ are computed, where two lines are incident if and only if they are skew.
