I have finally proven how many ways there are to choose rows of the Sierpinski matrix of order n such that the rows form a system of linear equations with 0 degrees of freedom.

It turns out valid selections from [math]S_n[/math] are in bijection with full binary trees of depth n.

So, there are A002577 of them.
