[#R513] Exact Vieta enumeration connects every G_p for 5 <= p <= 3001

claim. A full breadth-first search visits all 1,169,185,980 nonorigin surface points across all 429 primes with 5 <= p <= 3001 and finds one component at every prime.

1Summary

For each prime \(5\leq p\leq3001\), the linked program constructs every point on \[ x^2+y^2+z^2=xyz \] by solving the quadratic in \(z\), removes only \((0,0,0)\), and follows exactly the three stated Vieta involutions. It checks the point-count formula \[ |G_p|=p^2+3p\left(\frac{-1}{p}\right) \] and the zero-coordinate count, then starts breadth-first search at \((3,3,3)\). Every one of the 429 rows has one component whose size equals the checked point count.

The output also retains a shortest move word to a lexicographically selected farthest vertex. The largest recorded root eccentricity is 27, attained at \(p=2711,2749,2909\). At \(p=2711\), the word `121213123123213132131212312` takes \((3,3,3)\) to \((1123,2036,2036)\).

Reproduced evidence. Recorded scope: every prime p with 5 <= p <= 3001 for the coefficient-one Markoff surface and the three stated Vieta edges.
