Awesome, I didn’t want to ask directly, but I’m excited to hear of your
interest in looking into the problem of the number of permutations! I
wonder if this particular calculation has ever been done before. Also, I’ve
seen and used big number calculators on the web before, so I also had to
wonder how easy it would be to find one that would be able to show all the
digits in the final answer to this problem. I hope one is out there.
