Leyland Primes: ECPP proofs
Placeholder for xy+yx prime proofs.
http://www.primefan.ru/xyyxf/primes.html#0 There are some PRPs available starting from ~6600 digit size. Contact XYYXF to reserve. Last fiddled with by XYYXF on 2015-02-02 at 15:03 Reason: added an URL to the list of primes and PRPs |

There are a few existing reservations that make one very curious:
222748^3+3^222748 (a 106278 decimal digits PRP by Anatoly Selevich) is reserved by Jens Franke. Is it that the low value of y=3 makes for a very special case for a ECPP proof? |

AFAIK, they're going to make a CIDE proof, as it was done for 8656^2929+2929^8656:
