How would you say r (or any other lower case letter).
Literally just "ar" and "three ar" / "four ar" etc. There's basically no risk of confusion, although if disambiguation is really necessary, I'd probably say "ar wide", "three ar wide", etc. for the wide moves and "two ar", "three ar" for the slice moves. Basically, just reading SiGN / WCA notation out loud.What about for puzzles that could have multiple types of r wide (bigger than 3x3?)
