Next Puzzle Hunt!

My next math puzzle hunt will be on March 24! Hope everyone can make it!

In the mean time… another problem I came across:

How many positive numbers between 1 and 100000000 have the same number of 0’s, 1’s, 2’s, and 3’s as digits such that no leading zeros are allowed?

Interestingly enough this was a computer science problem, but see if you find a solution using strictly math.
