BGG resolution formula for $L_c((2n),\emptyset)$

Let $W=B_{2n}=G(2,1,2n)$ and let the parameter $c=1/(2n)$ be constant. Write $\Delta_i$ and $\Delta_{2n-i}$ for the standard-module sums specified in the preceding theorem, and let $L_c((2n),\emptyset)$ be the corresponding Cherednik algebra simple module. BGG resolution conjecture. For $0\leq i\leq n$, the $i$th term of the minimal BGG resolution of $L_c((2n),\emptyset)$ is $\Delta_i$, and the $(2n-i)$th term is $\Delta_{2n-i}$.
