Leyland Primes (x^y+y^x primes) - Page 14

NorbSchneider · 2016-04-21, 09:14

The interval 12,501<=x<=13,000, 3001<=y<=x-1 is done, no new PRPs.

In the interval 50,001<=x<=500,000, 19<=y<=25 reached I x=206,000, no new PRPs.

I continue the search in the interval 20,001<=x<=50,000, 401<=y<=800.
Please reserve this interval for me.

Note: I moved posts about y^x-x^y primes to the new thread of their own.

Some posts dealt both with - and + forms, so these were duplicated in both threads; no data was lost.

Thank you Serge :)

L(13318,5527): If anyone is getting annoyed by my posting these as I find them, let me know. I've got a good start on doing all gaps less than L(12310,11641). As these finish, I'll switch over to the additional gaps less than L(19312,429).
