Webb13 juli 2024 · One can create a permutation of this new sequence by considering a permutation of the sequence ( s 1, s 2, …, s n) and adding to it the element s n + 1, whereby we have n + 1 possible positions where s n + 1 could be placed. Since we do this for every permutations of the sequence ( s 1, s 2, …, s n) we obtain ( n + 1) ⋅ n! = ( n + 1)!. flame botany junction
