Padé continued-fraction coefficient matching conjecture

Let ama_m be the sequence of numbers generated by Theorem 3, and let gm(n)g_m(n) be the associated finite continued fractions. Let B(n)B(n) denote the continued fraction obtained from the Stirling series by the quotient-difference algorithm, with numerator sequence (bm)(b_m).

Coefficient matching conjecture. In the limit as mm tends to infinity, the continued fraction gm(n)g_m(n) agrees with B(n)B(n); equivalently, their numerator sequences satisfy

am=bm.a_m=b_m.

This conjecture arises from the observed agreement between the coefficients produced by the telescoping method and those of the SS-fraction for the diagonal Padé approximants to the Stirling series. No proof or disproof is supplied in the excerpt, so the conjecture remains open.
