Let $Q$ and $Q'$ be symplectic quandles of the same dimension over the ring $\mathbb{Z}_n$. They are isomorphism–isometry conjecture. Isomorphic as quandles if and only if they are…

For each prime $p$, let $T_p=((\mathbb{Z}_p)^2,\lambda_pJ)$ be a symplectic quandle, where $\lambda_p\in\mathbb{Z}_p^\times$ may depend on the link crossing number. Let $H$ be the…
