in reply to Re: extracting all possible n-mers from an array
in thread extracting all possible n-mers from an array

for some reason i immediately thought of colour pallettes.
not the nicest code, but something i knocked up quickly using your algorithm:
my $c; my $cols={map{(chr(65+$c++),sprintf "%02x",$_)}(0, 51, 102, 153, 204, + 255)}; my @letters=qw/A B C D E F/; print "<html><body><table border=1><tr>"; $c=0; for(glob "{@{[ join ',', @letters ]}}" x 3){ s#.#$cols->{$&}#eg; print "<td bgcolor='#$_'>&nbsp;</td>\n"; print "</tr><tr>" if !(++$c %9); }; print "</tr></table></body></html>";
