For example I want a permutation generator that can support 9 columns. Some columns will have the same information but not to repeat. Will give an example at below.
Column (1) type of grass: Monkey Grass, Blue Grass, Fescue, Bermuda.
Column (2) type of equipment: Lawn mower, Hedgers, weed eater, aerator, leaf blower.
Column (3) type of equipment: Lawn mower, Hedgers, weed eater, aerator, leaf blower.
Column (4) workers: Lisa, Alex, John, Jim, Michael, Jose, Oscar, Ashley, Shirley.
Column (5) workers: Lisa, Alex, John, Jim, Michael, Jose, Oscar, Ashley, Shirley.
Column (6) workers: Lisa, Alex, John, Jim, Michael, Jose, Oscar, Ashley, Shirley.
Column (7) hours worked: 1, 2, 3, 4, 5, 6.
Column (8) Pay: $12, $13, $14, $15.
Column (9) Type of payment: Check, Cash, Direct Deposit, Wire.
Example of what I do want:
Monkey Grass, Lawn Mower, Hedger, Weed eater, Lisa, Alex,1, Check.
What I don't want:
Monkey Grass, ((Lawn Mower, Lawn Mower,)) Hedger, Lisa, Alex, 1, Check.
I do not want any repeating information like ((Lawn Mower, Lawn Mower)) in the same permutation.
