Just saw this thread. Here is a destructive (only works once) solution at 46:

sub nn{$a|=$"x$_.1for@_;$b.=$"until$a=~/1$b(1)/;@a=@-}

Ah, I should think a bit more before submitting. Here is a 44 (and I should also mention it only works for smallish natural numbers, all different and at least 2 arguments):

sub nn{$a|=2x$_.3for@_;$b.=2until$a=~/3$b(3)/;@a=@-}

The need for the assign is a perlbug, otherwise it would be 41
