I would expect any of the following:
hello,hi,othello,brake,rake,raker,rash,ash,hash,ohio,
the,lob,bra,hell,era
I don't see how you could expect some of those strings, because some only appear once in the string (e.g. "othello", "ohio"), so you really couldn't call them a "pattern" unless you're matching against a dictionary file.
My solution near the top of this thread sort of assumes that the string is a contiguous series of patterns (one of the original constraints was "String contains nothing but patterns"), so it only finds "hello" from your test string, but if you change this line: # From this
if (/\G(.{2,})(?=.*?\1)/g) {
# To this
if (/\G.*?(.{2,})(?=.*?\1)/g) {
Then it does better and finds "ash", "rake", and "hello" from your test string, which is about as good as it gets, I believe.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
