   • 2015, Jonathan Lorand, Alan Weinstein, “Decomposition of (co)isotropic relations”, in arXiv‎^[1]:

     We also find a list of thirteen invariants, each of which is the dimension of a space constructed from the relation, such that the 13-vector of multiplicities and the 13-vector of invariants are related by an invertible matrix over $\mathbb {Z}$. It turns out to be simpler to do the analysis above for isotropic relations between presymplectic vector spaces.
