Abstract

There are 38975 Fermat pseudoprimes (base 2) up to 1011, 101629 up to 1012 and 264239 up to 1013: we describe the calculations and give some statistics. The numbers were generated by a variety of strategies, the most important being a back-tracking search for possible prime factorisations, and the computations checked by a sieving technique.
