| Feb 20, 2021 at 23:05 | comment | added | LSpice | I added a link to the MSE question, and, in the process, converted your manually spaced inline math (which I found very hard to read) into the relevant AMSmath environments. I hope that was all right. | |

| Feb 20, 2021 at 1:27 | comment | added | Will Jagy | getting systematic about it. Found one with a quick proof, $\langle 5,4,8 \rangle$ because the duplicated form is $\langle 4,0,9 \rangle$ and there are only finitely many solutions to $w^2 - 9 v^2=4$ or $w^2 - 4 v^2 = 9$ Two more from that page $\langle 5,2,13 \rangle$ $\langle 6,2,11 \rangle$ | |

| Feb 19, 2021 at 17:36 | comment | added | Will Jagy | right. The values indicated by the square root signs in my comment last night come out $1, 7, 17, 19, 23 \pmod {24}$ while the values of $14 x^2 + 8xy + 29 y^2$ that are coprime with $24$ are $5, 11 \pmod{24}$ | |

| Feb 19, 2021 at 2:12 | comment | added | Will Jagy | the integers $\sqrt{39 + 10 v^2}$ and $\sqrt{10 + 39 v^2}$ come out wrong, either $\pmod 3$ or $\pmod 8,$ for values of $14 x^2 + 8 xy + 29 y^2.$ The form is alone in its genus, factoring does not matter...so weird | |
