If you’re a mathematician and you have a conjecture, constant, equation, function or theorem named after you, you can be proud of yourself. If you’re Euler, that’s 3 conjectures, 11 equations, 9 formulas, 4 functions, 2 identities, 10+ constants, 11 theorems, and 2 laws, some of them shared with others (https://en.wikipedia.org/wiki/List_of_things_named_after_Leonhard_Euler https://en.wikipedia.org/wiki/List_of_things_named_after_Leo...) That includes https://en.wikipedia.org/wiki/Euclid–Euler_theorem https://en.wikipedia.org/wiki/Euclid–Euler_theorem, which must have been one of the ‘cooperations’ (Euclid died ±270BC, Euler lived 1707-1783, and his proof was published posthumously) on a theorem that took the longest time in history.
