A double-check using PFGW with a different PRP base is in progress - to ensure that there were no missed primes.

Extending the Chris K. Caldwell and Yuanyou Cheng, <a href="http://www.cs.uwaterloo.ca/journals/JIS/VOL8/Caldwell/caldwell78.html">Determining Mills' Constant and a Note on Honaker's Problem</a>, Journal of Integer Sequences, Vol. 8 (2005), Article 05.4.1, the Mills' constant value could be determined with more precision.

Congrats, Serge, on your fine probable prime, for Henri.

... is the 13th Mills' prime.

Not proven to be so, nor likely to be proven so,
for a long time, as you fully know.

Best regards
