After a small hiatus, on December 10 I started again to look for Leyland primes. I have now finished with the Leyland numbers in the gap between L(19021,1576) <60821 digits> and L(29007,128) <61124 digits> and have found therein 6 new PRPs:

L(14708,13707) <60847>
L(15088,10831) <60876>
L(14858,12651) <60950>
L(16069,6258) <61005>
L(14788,13355) <61011>
L(16697,4570) <61110>
