Well, I had thought that perhaps Algorithm::Permute might be the answer, but according to its documentation, so far it only deals with n arrangements of n items. Given that, and the amount of time it can take for even a small set of matches, I tossed together the following, based fairly closely on its docs. I *DO NOT* recommend this method (because it is highly inefficient, in just about every way I can think of). 

#!/usr/bin/perl -w

use strict;
use Algorithm::Permute;
$| = 1;
my @spinner = ('|', '/', '-', '\\');
my $bigscale = 100_000;
my $scale = 100;
my $index = 0;
my $draw_max = 9;
my $draw_min = 1;
my $to_draw = 6;
my (%seen);
my (@res);

  my $p = new Algorithm::Permute([$draw_min .. $draw_max]);
  while (@res = $p->next) {
    my $st = join(', ', sort(@res[0 .. ($to_draw - 1)]));
    $seen{$st} = 1;
    print $spinner[($index++ / $scale) % 4], "\b";
    print '.' unless ($index % $bigscale);
  }
  print join "\n", sort keys %seen;
