Hello! I was wondering if there is a way to generate multiple columns of random numbers that may repeat within the column, but not within the row. Eg: 3 columns x 80 rows, using the numbers 1-9, where "1,7,7" would not be an acceptable row. It would also be helpful if I could tell Excel to include one number from 1-3 and 2 numbers from 6-9 per row. I know the basics of generating random numbers and non-repeating columns, but wasn't sure about how to automate creating this sort of matrix.
