All primes are equal, but some primes are more equal than others.

So are 0 and 1 on or off?
According to the binary configurations, 1 typically refers to on and 0 usually means off. Last fiddled with by tuckerkao on 20210824 at 22:42

The only prime with the binary0 ender is 10_{2}. All others have the unitdigit of 1: 11_{2}, 101_{2}, 111_{2}, 1011_{2}, 1101_{2} ...

Maybe a number can be simultaneously prime & composite. (When I first saw someone put a picture of a cat, I thought it was going to be Schrödinger's cat)

The only Senary primes with the exceptions are 2 and 3. All others have the unitdigit of 1 or 5: 5, 11_{6}, 15_{6}, 21_{6}, 25_{6}, 31_{6}, 35_{6}, 45_{6}, 51_{6} ...
Senary base has a specific strength which is to be able to notice the multiples of 2 and 3 very quickly and possible on 5 (base  1) and possible on 11_{6} (base + 1) or decimal 7. Combine the above Senary line with the binary line, then you'll get the base I like the most. Last fiddled with by tuckerkao on 20210824 at 23:25

https://www.mersenneforum.org/showpo...0&postcount=79 leading to a glossary entry for Schrödinger number. Can cats count? There's some evidence mine can, at least to 4.
