How to generate 750,000 unique random 6 digits alphanumeric numbers without duplicates?

Hi,

I want to generate total 750,000 unique random combination of alpha and numeric numbers without duplicates, without using "O", "0", "1", "i".
The number of digits is 6 (3 number 3 alphabet).
Random position and combination among this 6 digits.

Is there anyone here can teach me how to do it?



Thanks!
