Non-isomorphism conjecture for quandles constructed from an infinite-type quandle

Let $Q$ be an infinite type quandle. For each positive integer $n$, let $d4ac_n(Q)$ denote the quandle constructed from $Q$ at level $n$.

Non-isomorphism conjecture. The quandles $d4ac_n(Q)$ and $d4ac_m(Q)$ are not isomorphic whenever $n\neq m$ and $n,m\in\mathbb{Z}^+$.

This conjecture asserts that the construction produces pairwise non-isomorphic quandles from an infinite-type quandle. The supplied text gives no information about whether it has been resolved.
