It can be composed of 0, 4, 5 and 8______ 548 is the third of three different digits______ One

The three digits are: 4 in the hundreds: 4054084584450480485; 5 in the hundreds: 504508548580584; 8 in the hundreds: 80480584084585854; there are 18 kinds; from small to large, 548 is the 10th; so the answer is: 18, 10

We can make up many four digit numbers with the four numbers of 6, 7, 8 and 9, and arrange them in order from small to large. Then, which number is 9768
It's better to have a formula

The four digits of these four numbers are 4 * 3 * 2 * 1 = 24
