The first mega prime of 2016 is also the first SR5 of 2016!

306398*5^2112410-1 eliminates 306398 from the Riesel base 5 problem. 77 values remain.

Congratulations NocFlame!

Congratulations to 288larsson for finding our 6th SR5 prime of the year, and our 29th mega prime overall for 2016. That ties the our record for most mega primes discovered in one year, set in 2014.

The prime 180062*5^2249192-1 eliminates k=180062 from the base 5 Riesel problem. 74 ks remain.

This is largest known base 5 prime, and the 48th largest known prime overall.
