Hello,
Hope it is here I have to post this...

I wonder if you know a routine like the one I'm trying to develop?
A spectator thinks of an object (map, color, shape ...) in 5 that are presented on the table. It swaps the other 4 2 2.
The magician finds the object "thought."
I know a routine with three items, but with 5?
This to include credits if publication.
Thank you ...
