Nine triangles, twenty-four triple intersections, and the figure almost nobody draws correctly
The tradition states nine conditions where only five are free. Every modern account states fewer than five. Both are wrong in opposite directions — and the tradition’s four surplus conditions are not error, they are evidence about which member of the family was intended.
Thirty-two chapters and five appendices, 64,790 words. Part I and the verse chapter are free to read — the problem, and what the tradition actually says about it. The complete text is the printed edition itself, and opens with any licence; the evidence behind every claim stays free in the library, exactly as the printed copyright page promises.
Synced from Book/chapters/ on 2026-08-09 — the same files the print edition is typeset from, so the two cannot drift apart.
