How can I list, matchings 'sets' of numbers?

I would like a to list each row that has a matching set of numbers with another row in a spreadsheet.

For example: Rows (1) and (4) have the numbers 4,6,7 and 9.
And rows (2) and (3) have the numbers 5,2,1 and 3.

__ A B C D
(1) 4 6 7 9
(2) 5 2 1 3
(3) 5 2 1 3
(4) 4 6 7 9
(5) 2 5 9 7


I'd like to be able to highlight or list every row that has the same group of numbers as any other row in the spreadsheet.

Something like - if the numbers in rows 1:5 match the numbers in any other row, then highlight or list the rows.

Thanks in advance :-)
