COMMENTS

Numbers are 11 mod 24.

Jon Grantham: "I strongly believe that some sub-product of these primes is a Carmichael number and a Lucas pseudoprime for the Fibonacci sequence, and also is 2 or 3 mod 5."

In particular the above conjecture implies that there is a BPSW pseudoprime smaller than 10^25286. - Charles R Greathouse IV, Sep 28 2019
