How can I select a Random Number within a group and make that selected number unique among other groups?

[cheyennemtnman]

1) 9 groups of 4 numbers (integers)
2) Each integer value less that 10
2) Each number is unique within the group
3) Multiple Groups can have same number(s) Group A 1,3,7,5 - Group B 2, 5, 8, 9- etc.

Want to randomly select a number within group of 4
But each group must have a unique resulting number between the groups.
(i.e. no group can have the same resulting number)

How many numbers do you want to select?

One from each group and each number must be unique
