[QUOTE=GP2;502686](2^1430131+1)/(3*356468732537*36519993971459) is a 430487-digit PRP

I'm going on work on ranges below 1M next.[/QUOTE]

Tesla V100 is really fast. :smile:

In the range from 500k to 1M there were 8541 new second-and-higher factors of size 56 bits or less, and two new PRPs:

(2^730339+1)/(3*27839062003*7943469324347)
(2^758231+1)/(3*27146942976539*73236839266867)

In the 1M to 2M range earlier, I found 16143 new second-and-higher factors of size 57 bits or less, plus the PRP cofactor of exponent 1430131.
