    The following set contains 128 12-bit integers where w( x ^ y ) >= 5 
    31 32 64 96 128 160 192 224 256 288 320 352 384 416 448 480 512 544 576 608 640...

    check your program, w(32 ^ 64) is 2 < 5

      Grrr. You're right! There is a big difference between: 

              my $n = unpack '%32b*', ( $set[ $x ] ^ $set[ $y ] );

      and 

              my $n = unpack '%32b*', pack 'N`', ( $set[ $x ] ^ $set[ $y ] )
+;
