> 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...
