Let $\Sigma$ be the $d$-Weddle scheme associated with a general set of $\binom{d+n}{n}$ points in $\mathbb{P}^{n+1}$, as in the preceding theorem. Reducedness and irreducibility co…

Let $d\geq 2$ and let $Z$ be a set of $\binom{d+2}{2}-1$ general points in $\mathbb{P}^3$. The $d$-Weddle scheme is the locus of points $P$ for which the projection $\pi_P(Z)$ lies…
