in reply to Finding repeat sequences.

> Eg. In abcdabcdabceabcdabcdabceab; abcd is a false rep; the required rep is abcdabcdabce;

since regex are greedy, this works for me

DB<131> $_='abcdabcdabceabcdabcdabceab' => "abcdabcdabceabcdabcdabceab" DB<132> ($match)= /(.+)\1/ => "abcdabcdabce"

edit: I doubt that the answer is so simple, but this should give you a start to ask more precisely...
