My guess is that 147 must appear the same number of times as 258, but I'm not sure if that's even expressible in regexp.

- recursive 13y agoNo. 111 is a multiple of 3.
- johnlbevan2 13y agoSadly that wouldn't work for: 140091876 147 = 4 times 258 = 1 time
- johnlbevan2 13y agoRefined: [0369] can appear any number of times [147] and [258] must appear an equal number of times, or for any remaining: [147] must appear a multiple of 3 times [258] must appear a multiple of 3 times
