what's the pattern on "Abba"? I thought it was just to exclude doubled letters but I have doubles on two words on the left hand side as well (noisefully and effusive, in case the word lists are the same)
^(.)(.).*\2\1$Earlier quoted context omitted.
It gives you hints below the score, for 6 it's: You're allowed to cheat a little, since this one is technically impossible. No idea how you cheat... EDIT, SPOILERS: I get 170 with ^(.?)(.)(.).?\3\2\1$
176 with ^(.)(.).*\2\1$
^(.)[^p].*\1$ # 177, "cheat a little"I got Four for 196 with (.).*\1.\1.*\1 and Order for 156 with ^a*b*c*d*e*f*g*h*i*j*k*l*m*n*o*p*q*r*s*t*u*v*w*x*y*z*$
^[a-g]*[^a-g]*$I have the most trouble with regex, and something about seeing my matches as I type made this incredibly useful for me!

well, if you are strictly interested in matching with the fewest characters, regardless of the apparent pattern: ^(.)(.).*\2\1$

Excluding doubled consonants that have the same vowel on both sides of the pair: ^((?!([aeiou])([^aeiou])\3\2).)*$ The following also works for the testcases and is shorter: ^((?!(.)(.)\3\2).)*$
ef|^((?!(.)\2).)*$
