I have now finished testing the Leyland numbers in the interval from L(302999,10) to L(303999,10) and have found therein 14 PRPs. Next interval is L(303999,10)  L(304999,10).

To Norbert & Ighu: Have either of you been getting email confirmations for your PRPtop submissions? I had a time in mid to lateDecember when I wasn't getting them and then, again, starting in midFebruary. In fact, I've had no confirmation since then even though they were all received.
