Well, I'm partial to squares (4, 9, etc.) because of the open locker problem*, among other reasons.
Also, DNA is base 4, so it's sort of built-in.![Tongue Tongue](https://forum.bitbusters.club/images/discord/tongue.png)
* Take 100 school lockers (numbered 1-100). Open every one. Close every second one. Toggle (open or close) every third one, etc. Which lockers are left open at the end?
