| Sep 30, 2022 at 7:13 | comment | added | David Loeffler | That is already answered above. If $n$ is squarefree and $3 \bmod 4$, then the implication "$h_n$ is odd iff $n$ is prime" holds. | |
| Sep 30, 2022 at 6:56 | comment | added | user492144 | Leoffler Is there a known characterization of particular class of $n$ for which if the class number is odd then $n$ is always a prime? Say, if $n\equiv11\pmod{24}$, then, $h_n$ is odd if and only if $n$ is a prime? Thanks! | |
