@evan yeah. Strange result. Even 23 is more 5 than 25 as any Robert Anton Wilson fan knows. https://discordia.fandom.com/wiki/Law_of_Fives
But of the choices 55 is obviously the most 5 as it even contains the first two options. Add them to get 10 or multiply them to get 25. So 55 contains all the fiveness of those options plus more of its own.
