Family 237. The three-quarter diameter exponent for honeycomb walks.

The authors are OpenAI. This companion does not verify the proof and does not adopt it as a theorem of Ngo Cheung’s series. It is not a premise. O.1 stays NOT_CLOSED. Anti-de Sitter results are not a de Sitter state, not Em02-E’s relational lapse, not XVI-P’s QdS scheme, and not XVI-Q’s sigma-image record. No quantum coefficient is admitted. No compilation is asserted.

Proves the diameter form of Nienhuis's predicted three-quarter exponent: a uniformly chosen $n$ -step self-avoiding walk on the honeycomb lattice has diameter $n^{3/4 + o (1)}$ . Its local mass and covering numbers have exponent $4/3$ . These estimates hold at every sufficiently large fixed length, simultaneously across scales, with arbitrarily high polynomial probability.

At the critical honeycomb fugacity, self-avoiding port-to-port chords in an equilateral lattice triangle of side R, summed over both boundary endpoints and restricted to diameter at least $R /100$ , have partition sum comparable to R3/4 and mean length $R^{4/3 + o (1)}$ . We also determine the amplitude selected by two vacuum caps on a cylinder of circumference N and prove that it grows as $N^{1/6 + o (1)}$ .
