Good postulation conjecture. A finite union of general codimension $2$ linear subspaces in $\mathbb P^N$ has good postulation.

Let $\mathbb{H}^n=\{0,1\}^n$ be the vertices of the $n$-dimensional hypercube, and let $H(n,k)$ be the set of intersection sizes $|\mathbb{H}^n\cap S|$ as $S$ ranges over the $k$-d…
