Yes thank you. I am looking for numbers of "reasonable" size to prove with
Primo this summer, in order to stay on the top 20 list for the program.
There are two PRP of that form, and I just wanted to make sure nobody was
working on them.
So far we know that 10^n-17 is prime for n=1, 2, 3, 6 (found with PFGW),
n= 30, 40, 86, 128, 264, 639, and 912 (found with Primo and PFGW)
1932 will be known later today, and n=4650 and 5038 I am probably going to
test this summer.
Thanks for pointing me to Milton's work. I doubt he'll be beating me to
any finds since when I knew him he had little interest in actually proving
