Hi again

I've got this part of my program, which is meant to go through all possibilities of w, x, y, z, except for when they're evenly spaced apart, or in arithmetic sequence if that makes sense to you. Since I already know those cases won't give me what I'm looking for I want to save perl the trouble of considering them. Here's what I've come up with, but I have a feeling there's a way to make it go faster. I wonder if I really need that s variable since it's just one more thing to deal with:

foreach my $w (3..100) {
    foreach my $x (2..$w-1) {
        foreach my $y (1..$x-1) {
            foreach my $z (0..$y-1) {
                
                foreach my $s (1..20) {
                    unless ( $x == $w + $s && $y == $x + $s && $z == $
+y + $s ) {

I can add more context if you want, this is just part of the program which works fine I just thought I'd see if there's a way to streamline it.

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).
