No cookie for me I just tried it in Notepad++ and VS code and it matches lines of one characer (first group I think) or the starting of a line that is an at least 2 characters string repeated twice (second group it seems)
so the second group matches
abab
abcabc
abcdeabce
abcdefabcdef
Nothing about prime numbers really only first repetition gets a match. Very interesting Honestly I used regex from years and never had to retort to something like this ever.
I can only imagine it useful to check for a password complexity to not be repeated strings like I do for sites that I just want in and use a yopmail.com mail to register a fake user.
Yes but the match goes for the first repetition the rest of the string isn’t matched no matter the length, again don’t find anything about prime numbers unless I checked something wrong. There is another guy who got it right it seems.

“at least 2 characters repeated [at least] twice” implies the string’s length is divisible by a number greater than 1.
