 As mentioned above at [Mlucas build notes](#mlucas-build-notes), building Mlucas is highly architecture-specific, and some 
 build types will not support all of the optimal FFT lengths.
 
-Finally, 2K appears to be the smallest usable FFT for the smallest testable Fermat number _F_<sub>13</sub>, with the command line settings `-fft 2 -radset 8,8,16 -shift 0`.
+Finally, 2K appears to be the smallest usable FFT for the smallest testable Fermat number _F_<sub>13</sub>.
 
 The 4K FFT seems to be more reliable on a wider range of systems for the next larger Fermat numbers _F_<sub>14</sub> to _F_<sub>16</sub>.
