Abstract: There are 105212 Carmichael numbers up to $ {10^{15}}$: we describe the calculations. The numbers were generated by a back-tracking search for possible prime factorizations, and the computations checked by searching selected ranges of integers directly using a sieving technique, together with a "large-prime variation".
