www.todayifoundout.com/index.php/2012/11/math-tricks/ Read it. The 1st phase says how to find if a number divisible by 11.

3267. Theres (3 + 6) - (7 + 2) = 0 Which is divisible by 11.

So a permutation would be 3762. You can switch 3 and 6 and then 7 and 2. There you end up with 4 permutations.

And you can take this too as a permutation. 7623. ( 7+ 2) - (6 + 3) = 0 Which is divisible by 11.
