4 objects taken 4 at a time is "4!" This is read "4 factorial" and is 1*2*3*4=24
One fourth of them, or 6, of these numbers are going to start with 0, so they have to be removed.
The answer is 18. {4067, 4076, 4607, 4670, 4706, 4760, 6047, 6074, 6407, 6470, 6704, 6740, 7046, 7064, 7406, 7460, 7604, 7640} ■
It could be: 4760 = 1
4067, 4076, 4607, 4670, 4706, 4760, 6047, 6074, 6407, 6470, 6704, 6740, 7046, 7064, 7406, 7460, 7604, 7640.
3 x 4 x 4 x 4 = 192 of them
Heres a few: 4760, 47600, 476000000000000.
