| Jun 12, 2021 at 17:56 | comment | added | Noam D. Elkies | It can be hard to tell at sight whether such an equation is recreational or research-level. Occasionally even published papers that apply advanced methods to this kind of equation turn out to be replaceable with elementary arguments. There's probably little harm in keeping this Q&A in mathoverflow. | |
