You will run out of rows. Assuming you want the numbers grouped in groups of 10 e.g. 1,2,3,4,5,6,7,8,9,10 and then 1,2,3,4,5,6,7,8,10,9 etc. Then you will run out of room in Excel about 30% the way through - By my estimation there are 3,628,800 combinations, but only 1,048,576 rows in Excel (2007).
