Things that at least seem to be the case
Plausible:
  • The rule doesn’t care about anagrams
  • Case doesn’t matter
  • You need at least one letter
  • You need more than one character
Less plausible (I expect these patterns are an artifact of our specific tests, not of the rule itself):
  • You need at least two letters
  • You need more than two characters
We could probably gain the most information by proving one of the plausible patterns wrong, but I’ll focus on the ones I marked less plausible because it’s correspondingly more likely I can find a counterexample.

The rule also probably has something to do with the letter R, all yesses have it.

We are missing a lot of letters.

I do not expect any of these to be yes, for reasons I outlined above. But it would be nice to be surer.
