The type C rack conjecture for finite Nichols algebras

Let $\mathcal{O}$ be a finite rack of type C, let $\mathfrak{q}$ be a faithful $2$-cocycle on $\mathcal{O}$, and let $\mathscr{B}(\mathcal{O},\mathfrak{q})$ denote the associated Nichols algebra. Type C rack conjecture. Then

$$\operatorname{GK-dim}\mathscr{B}(\mathcal{O},\mathfrak{q})=\infty$$

for every faithful $2$-cocycle $\mathfrak{q}$. The conjecture predicts infinite growth for Nichols algebras arising from finite racks of type C and is part of the program classifying finite-Gelfand–Kirillov-dimensional Nichols algebras.
