Take b = 2.
b^(n-1) mod n = 1.
1254043595354617963043866617659 is prime.
b^((n-1)/1254043595354617963043866617659)-1 mod n = 5991785192639272703656031650832898593729272639365829891762926024204243701911, which is a unit, inverse 16441383361602209521167148029114335627594786737420330521198003941761943890955.
