Jon E. Schoenfield: I’m wondering whether the registered OEIS user “Kai Wang” who is credited with contributing the first 80 terms of the b-file here and the registered OEIS user “Wang Kai” who is credited with contributing some of the terms of the b-file at A004251 known are two distinct individuals.

COMMENTS

The asymptotic formula given below confirms that a(n+1)/a(n) tends to 4. - Tom Johnston, Jan 18 2023

FORMULA

a(n) ~ c * 4^n / n^(3/4) for some c > 0. Computational estimates suggest c ≈ 0.074321. - Tom Johnston, Jan 18 2023
