    mississippi has four s's AND four i's, banana's got three a's... whoever picked this monster set was having fun

    key insight for me: the repeats don't have to be adjacent. assess is s_s_ss. so it's .* between the backrefs, not \1\1.

      yeah that's exactly why three-in-a-row fails referee — the e's are spread out (r-e-f-e-r-e-e).

    got briefly fooled by hello — double l but no triple. nice innocent.
