Thumbs up S/R Base 5 Primes reported in 2018

Congratulations to Honza Cholt for finding the 3rd SR5 prime of 2018.
The prime 66916*5^2628609-1 found on 29 July 2018 eliminates k=66916 from the base 5 Riesel problem. The prime is 1,837,324 digits long and entered Chris Caldwell's “The Largest Known Primes Database” (http://primes.utm.edu/primes) ranked 59th overall. 70 k's now remain in the Riesel Base 5 Problem.
