How can I have a method that calculates Ackermann Functions very fast?

Hi;

It would be extremely fast because the numbers grow very large, very quickly, so even with M you could only compute the first few.

For instance:

Suppose I am interested in the last 4 digits of A(4,4)?

Then I'd either find a very fast and powerful computer or do a lot of number theory.

You can probably get the last 4 digits.
