Abstract: In this paper we determine numerical values to 80D of the coefficients in the Taylor series expansion ${\Gamma ^m}(s + x) = \Sigma _0^\infty {g_k}(m,s){x^k}$ for certain values of m and s and use these values to calculate $\Gamma (p/q)\;(p,q = 1,2, \ldots ,10;\;p < q)$ and ${\min _{x > 0}}\Gamma (x)$ to 80D. Finally, we obtain a high-precision value of the integral $\smallint _0^\infty {(\Gamma (x))^{ - 1}}\;dx$ .
