Will the next number be R509?
Recently yoyo@home found two prime factors of R503 and one prime factor of R505, searched to ECM effort 60 digits and B1 = 85e7, will you also search to the same limit for R509, which has no single known prime factor?

R509 is checked with B1=260e6 and 45000 curves.
Factors up to about 60 digits should be covered.
For B1=850e6 is the number too big!
More curves with B1=260e6 are not useful and would be a waste of time!

Re: Will the next number be R509?
But both R503 and R505 (and also R507) are checked with B1=850e6 (I have seen your page https://kurtbeschorner.de/ecm-efforts.htm)
