 Some 5 number sets 2018-03-02 From Sarah:Hello! My question is: If I have 5 columns of numbers, and I want to create all possible combinations (or is it permutations?) How can I do that? For example all numbers in each column may not appear in any other column. so: column 1: 1,2,3,4,5 column 2: 6,7,8,9,10 column 3: 11,12,13,14,15 column 4: 16,17,18,19,20 column 5: 21,22,23,24,25 how may I determine all the possible ways I can get sets of 5 out if this?
