Using one idea I took from The Oldest Plays the Piano by casiano, I wrote the following script that returns those 6 combinations:
#!perl
use v5.10;
use strict;
use warnings;
my $objects = "12345";
sub f {
print join('|', @_) . "\n";
}
$objects =~ /^(.+)(.+)(.+)$
(?{ f($1, $2, $3) })
(*FAIL)
/x;
123|4|5
12|34|5
12|3|45
1|234|5
1|23|45
1|2|345
I don't think that this is a Diophantine equation, but it's still a freak way to solve this problem.
BTW, does the OP want other combinations like 13|24|5?

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).
