Some numbers behind chess#2

Hi, if you read Some numbers behind chess, you'll know what I'm doing. I have  some more imformation about the total number of legal chess positions. The total number of legal positions,(including positions where one side is in check) with each side having a king and one side having a pawn, not including promotions, is

788,080

I find that amazing. Again, I will keep you updated on what I find.
