Murphy Babb of the United States has found the second prime of the SR5 PRPNet Challenge. And what a nice one it is...coming in ranked 4th for SR5 primes and 265th overall in Top 5000 primes database!
This prime marks a nice milestone for the SR5 project. Removing k=183916 brings the sieve file to less than 3M terms remaining (to n=2M). The current sieve file has 2,982,533 terms in 181 sequences.
Only one more prime is needed to make 2010 the best year of the SR5 project in regards to prime score. If you are interested in participating, please see the Last 10 Days of 2010 PRPNet Challenge post.
