Examining the table, three general rules can be inferred: Rule #1: For combinations without repetition, the highest number of possibilities exists when r = n / 2 (k = n/2 if using that notation). It was introduced in MS Excel 2000. In a separate tab I want to generate a list of non-repeating combinations, order does not matter, and I want to run this list in varying string length (1x, 2x, 3x, 4x, .) To understand better the meaning and the use of the combination we are going to show the following example: If between 5 people we want to randomly choose two of them to participate in an act, in the permutation the order in which we pick the people would matter, for example, if we first pick the person A, and then the person B, this would one permutation, and if we pick the person B and then the person A, this would be another permutation, but in combination, this two scenarios would count only as one combination, no matter if the selection order is A and B or B and A.
