artist has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,
I have some items in array. Each item is group of 3 numbers. I like to find pair of items where no similar number between 2 items. For example [1,2,3] and [5,6,7] is ok but [1,2,3] and [2,4,6] is not ok. Any module would be useful also.

Thanks,
artist
