2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61.67の倍数を除いた素数候補式は 7858321551080267055879090n+Pで、
Pは、(2-1)(3-1)(5-1)(7-1)(11-1)(13-1)(17-1)(19-1)(23-1)(29-1)(31-1)(37-1) (41-1)(43-1)(47-1)(53-1)(59-1)(61-1)(67-1)個ある。

x=7858321551080267055879090j+Pで、x-2k=67のとき、
7858321551080267055879090j+P-2k=67
7858321551080267055879090j+(P-67)=2k

この関係は維持されるので、

ここで、
{(P-67)^33+1}
{(P-67)^33-1}
に注目する。

さて、Pは67でわれないから、
(%i1) P:67*u+t;
(%o1)                              67 u + t
とおくと、初式は
(%i2) factor((P-67)^3-1);
                              2                       2
(%o2)  (67 u + t - 68) (4489 u  + 134 t u - 8911 u + t  - 133 t + 4423)
であるから、
(P-67)^3-1から
t-68
t^2-133t+4423
に注目する。

また、(p-67)^69-1-{(P-67)^3-1}より間の
初式は、(P-67)^5-1となることもあり
初式は、(P-67)^7-1となることもあり
初式は、(P-67)^9-1となることもあり
        ・
        ・
        ・

初式は、(P-67)^68-1となることもある。

さて、循環するには、(P-67)^33+1か、(P-67)^33-1が67で割れなければならないから、
(P-67)^33+1か、
