Well, thanks! It's the second in a row, after n=363929 :cool:
Of course 7 is not "15k" (unless k=1/2 in integer division!) but I got presieved values from Thomas. With the new LLR one can go through low values of n quickly. Will be even faster if the program is not wasting time on vainly guesses of the FFT lenght... But still, we cannot complain.
