This isn't really a problem of combinations, it's a
printf problem. ;-)
The direct approach works just as well:
my $h = 0x33;
for my $i (0..5) {
for my $j (0..5) {
for my $k (0..5) {
printf"#%02x%02x%02x\n", $i*$h, $j*$h, $k*$h;
}
}
}
And the best I can golf that to is 77 chars:
for $a(0..5){for $b(0..5){printf"#%02x%02x%02x\n",$a*51,$b*51,$_*51for 0..5}}
As an aside, the common abuse of
$a and
$b in Golf isn't really in the spirit of strict even if it does give strict compliance.
