[math-fun] Weeks Between Easters

Long before even one round of the 5700000-year Gregorian Easter cycle is up, we will likely no longer use that formulation, assuming even that mankind survives that long. Nevertheless, as a mathematical entity - there it is, straddling the boundary between religious necessity and astronomical reality. When two separate Easters are one year apart, they can be 50, 51, 54, or 55 weeks apart. When they are 3 years apart, there are 5 weekly possibilities. When they are 10 years apart, there are 6 weekly possibilities. When they are 125 years apart, there are 7 weekly possibilities. Can there ever be 8 weekly possibilities?
