I think this does it? And should handle your real data without problems.

Updated: see comment for the one-line change.

#! perl -slw use strict; use Data::Dumper; sub combs { my @inputs = @_; my @saved = my @index = map{ scalar $#$_ } @inputs; my $next = $#index; return sub{ if( $index[ 0 ] == -1 ) { @index = @saved; return (); } my $rv = [ map{ $inputs[ $_ ][ $index[ $_ ] ] } 0 .. $#inputs +]; if( $index[ $next ] ) { $index[ $next ]--; } else { $next-- until $index[ $next ] or $next == 0; $index[ $next++ ]--; @index[ $next .. $#index ] = @saved[ $next .. $#index ]; $next = $#index; } return $rv; } } sub Cnr{ my $n = shift; return [] unless $n--; map{ my $x = $_; map{ [ $_[$x], @$_ ] } Cnr( $n, @_[ ($x + 1) .. $#_ ] ); } 0 ..

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
