| May 24, 2015 at 4:33 | comment | added | Geoff Robinson | That is the cyclic case. I the non-cyclic elementary Abelia case, (which you have to look further back for, working from the references in Jones' paper), there are infinitely many isomorphism classes when $ n >1.$ | |
| May 24, 2015 at 3:12 | comment | added | Mikhail Borovoi | There are infinitely many isomorphism classes for $n>2$. Anyway, thank you for the link, I did not know it. | |
| May 23, 2015 at 0:00 | comment | added | Geoff Robinson | There are infinitely many isomorphism types for $n >1.$ The number of isomorphism types is actually at least $1 + 2h_{p}$ when $n =1$, where $h_{p}$ is the class number of $\mathbb{Z}[\omega]$ and $\omega$ is a primitive $p$-th root of unity.
