Challenge: Generate 24 in the X register / display

[pinkman]

And now I’ve read the above messages and noticed that the rules, apparently clear and simple, were not.
Was it asked to find a solution for each digit from 0 to 9 as I did, or the best solution using 1 of the digits?
I also understand that each digit had to be used 3 and only 3 times, and I respected the rule with a few cheating, letting the unused digits on the stack (ie. 5).
