For example, if you have a set from 3 elements, {A, B, C}, the all possible combinations of size 2 will be {A,B}, {A,C} and {B,C}. These would be two different permutations. r! The generator allows selection of values $ k $ and $ n $, and generates possible lists of combinations with digits or letters (or a custom list). What is \newluafunction? In the random pairing generator you can choose if you want to generate a number of random combination or all possible combinations without repetition. = 3! The output columns are C, E, G, I & K. If we make 6 combinations then the 6th column would be M. The output should start from second row -> C2, E2, G2, I2, K2 (& M2 if we can go up to 6 combinations) This one can be explained with both Permutation and Combination. I guess the underlying idea I've used here lies in following the natural number sequence across the rows, and down the columns for the digits e and f also. 2 3 5 Example 1: A person is going to a candy shop where there are 8 types of flavors, if this person is only going to buy 3, define every combination possible. If its value less than n - m + i, it is incremented by 1, and all following elements are set to value of their previous neighbor plus 1 Type or paste objects into boxes with each object . That makes $10 \cdot 9 \cdot 8$. To create combinations without using itertools, iterate the list one by one and fix the first element of the list and make combinations with the remaining list.
