The archive in numbers
Lemma 1 · Complete cycle
pₙ₊₁ = (pₙ + 1) mod 237,537
Adding one has no common divisor with the archive size except one. The first choice therefore reaches every one of the 237,537 place pages exactly once before it repeats.
Lemma 2 · Six ways onward
D = {1, 97, 997, 10,007, 50,021, 100,003}
Each page offers these six forward distances. The distance of one preserves the complete cycle; the other five jump to far-apart parts of the same archive.
Lemma 3 · County total
Σ Ncounty = 237,606; unique pages = 237,537
The 32 county lists contain 237,606 placements. They become 237,537 different page addresses because 69 placements repeat an address already present in another county list.
