Silly me. Should have consulted with this: Permutations and combinations. 
use Algorithm::FastPermute;

sub combinations {
  return [] unless @_;
  my $first = shift;
  my @rest = combinations(@_);
  return @rest, map { [$first, @$_] } @rest;
} 

for(combinations('a'..'c')){
    my @c = @{$_};
    permute {print @c , "\n"} @c;
}

__END__

cb
