It was a legacy contruction from hacking together the code, To be more efficient by far I should pre-calculate 50000000*E in the second loop!

Another speed up might be had be putting !ispseudoprime() ahead of kronecker().

Anyway, I am now running with the bound 2250000000*E and have reached a=41. The only counterexample is the aforementioned one for a=4.
