Hi, Gerald H:

I have a programme that processes 720^20 in 5.6 sec.

Nice challenge, regrettably I can't take part in it because it asks for an RPL solution, which I can't provide. However, you say that your program processes 720^20 in 5.6 sec and that's *amazing* speed indeed for such a big number, so I'd like to ask the following:

How long does your program take to process the vey slightly smaller number 720^20-3 ? And how long for the even smaller 720^20-18 ?

Thanks in advance and have a nice weekend.
