How many one-to-one functions are there between A and B? If A has eight unique elements and B has ...
If A has eight unique elements and B has eight unique elements, how many one-to-one functions would there be?
Also, I'd like to know how many there would be if A happened to have less elements than B or if B had less elements than A.
Thank you for your time.
