Query: Stable linear systems of skew-symmetric forms of generic rank less than
  or equal to 4   Given a 6-dimensional complex vector space $W$, we consider linear systems of
skew-symmetric forms on W. The $n$-dimensional linear systems this kind, that
can also be interpreted as $n$-dimensional linear subspaces of
$\mathbb{P}(\bigwedge^2 W^*)$, are parametrized by the projective space
$\mathbb{P}(\mathbb{C}^{n+1}\otimes \bigwedge ^2 W^*)$. We analyze the $SL(W)$
action on this projective space and the GIT stability of linear systems with
respect to this action. We present a classification of all stable orbits of
linear systems whose generic element is a tensor of rank 4.
