The fitted asymptotic formula conjecture for peri-Catalan numbers

For a generator count ss, let PnsP^s_n be the number of reduced quasigroup words of length nn on ss generators and let CnC_n be the nn-th Catalan number. Consider the normalized limit

Ls=limnlogPnslogCn+nlog3slog3.L_s=\lim_{n\to\infty}\frac{\log P^s_n}{\log C_n+n\log 3s-\log3}.

Fitted asymptotic formula conjecture. For all generator counts ss, the limit exists and approximately satisfies

Ls10.019slog(1+52).L_s\simeq 1-\frac{0.019\dots}{s-\log\left(\frac{1+\sqrt{5}}{2}\right)}.

This formula is inferred from numerical data and a rational-function fit; it is intended to subsume the preceding unlabeled conjectures about the existence and dependence on ss of the normalized limits.
