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)

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?

Can you use ECM to factor these two numbers?
Can you use ECM to factor the composite cofactors of 13^282+1 and 13^288+1? Thanks.

Are there any interest to use ECM to factor Phi(365,10) and Phi(730,10)
See https://kurtbeschorner.de/ , yoyo home reserved many numbers Phi(n,10), including Phi(475,10), Phi(567,10), Phi(611,10), Phi(617,10), Phi(619,10), Phi(625,10), and yoyo home used ECM to find two prime factors of Phi(469,10), and Phi(469,10) is the second blank Phi(n,10) at that time, and the fir...
