I would use Algorithm::Combinatorics. 
#!/usr/bin/perl -l

BEGIN {
    $|  = 1;
    $^W = 1;
}

use strict;
use warnings;
use Data::Dump qw(pp);
use Algorithm::Combinatorics qw(partitions);

my(@data) = qw(a b c d e f g);

my $iter = partitions(\@data, 3, 4);
while (my $p = $iter->next) {
    print pp($p);
}
