Everyone who helped work on this. I really appreciate it.
I updated the b text file and made a note in the comment line that the
search only went to y<10^5.
Again, thank you for your efforts. Bob.
P.S. While looking at the y's, were there any which were not in A077426?

Another missing term:
y=3145;n=3955640265913618377915483821945263099722696409\
2919472362788156899442721839388657957656291679526667728\

8231504626853767310402979432;
and there is no more solution for y<10^5 and n<10^1000.
(Counted also 292 solutions up to 10^1000, in David's post and in b-file
there are two more solutions with 1001 digits, so at least 294 solutions for
n<10^1001)
