| Aug 27, 2018 at 23:59 | comment | added | KConrad | When $b=2$ this looks pretty close to the Riesel--Lucas--Lehmer test for primality of numbers of the form $k\cdot 2^n - 1$. See en.wikipedia.org/wiki/Lucas%E2%80%93Lehmer%E2%80%93Riesel_test. Note your $(4 \pm \sqrt{4^2-4})/2 = 2 \pm \sqrt{3}$. | |
