In that case you don't want a regex at all. Use substr.

use strict; use warnings; my $str = do {local $/; <DATA>}; $str =~ s/\s+//g; my $len = length $str; for (my $width = 5; $width; --$width) { for (0..($len - $width)) { print substr ($str, $_, $width) . "\n"; } } __DATA__ ABCDEFGHIJK

Perl is Huffman encoded by design.
