 Need Help??
I am sure there is a mathematical equation that would simplify this

Well, here's it. I hope it works. Has someone written a test program that compares the outputs of different solutions in this thread with each other?

```#!perl

use warnings;
use strict;

my(\$n, \$wd, \$fmt, \$x, \$y, \$r);
\$n = int(\$ARGV[-1] || 5);
\$wd = length(\$n**2);
\$fmt = "%\${wd}d ";
for \$x (0 .. \$n - 1) {
for \$y (0 .. \$n - 1) {
\$r = \$x <= \$y ?
\$x + \$y <= \$n - 1 ?
-4*\$x**2 + 4*\$n*\$x - \$x + \$y + 1 :
-4*\$y**2 + 4*\$n*\$y - 5*\$y + \$x + 2*\$n
+- 1 :
\$x + \$y <= \$n - 1 ?
-4*\$y**2 + 4*\$n*\$y - 7*\$y - \$x + 4*\$n
+- 3 :
-4*\$x**2 + 4*\$n*\$x - 3*\$x - \$y + 2*\$n
+- 1;
printf \$fmt, \$r;
}
print "\n";
}

__END__
