You are right to divide it in two cases. But the whole answer treats the two

6

's as different digits which they are not. Consider

6065

. This will be counted twice in your solution, once as

6_{1} 0 6_{2} 5

Here's a proof along the lines of your agument. Consider your special number (in your notation)

S = [1, 2, 3, \dots, (n - 3), (n - 2), n]_{n + 1} .

This number has

These are getting a bit long for comments, so: I'm not sure what you mean by 'all elements have been kept track'. For example, if

Ω = {1, 2, 3, 4, 5}

σ = (123) (45)

For this very special case, note that starting at 0 it must go 0,1,2,3,4 and then from 4 it might go back to 0, making the least

n > 0

P_{00}^{(n)} > 0

n = 5 .
