That is, if your combo is 4-26-3 you have to enter it in exactly that order to open the lock.

Since you can't enter the code into a lock in any order, a combination lock is actually a permutation lock. 5 Permute rows within bands If you permute the rows within the same band of a valid Sudoku board, you will obtain another valid board: 1 2 3 4 5 67 8 9 7 8 9 2 3 4 5. The best way to remember is: "a combination lock is a lie". Each chain closes upon itself, splitting the permutation into cycles. That is – combinations refer to how many subsets you can choose out of a whole set without caring about the order. Without using a calculator, determine the value of reject new a) 5 5x4x3x2x1. Combinations, however, are order agnostic. Permutations are closely related to the concept of combinations. If you are choosing a subset from a larger whole, it means how many ways you can choose the subset, and also how you can arrange your choice. If you already have an ordered set, the number of permutations tells you how many ways there are to arrange those members. 5 Using the Permutation Calculator What is a Permutation?Ī permutation tells you how many ways there are to arrange – and usually also, to choose a subset of – a set.
