If memory use is your only concern, then here's a rehash (har har har) of one of my prior atrocities...

$_ = 'acgnt' x 4; push @strings, "$1$2" while /.*(.).*(.)(?(?{$_{"$1$2"}++})^)/; push @strings, "$1$2$3" while /.*(.).*(.).*(.)(?(?{$_{"$1$2$3"}++})^ +)/; push @strings, "$1$2$3$4" while /.*(.).*(.).*(.).*(.)(?(?{$_{"$1$2$3$4 +"}++})^)/; print join $/, @strings;
