Abstract
In this paper, based on the Burnside’s formula, some accurate approximation and double inequality for the gamma function are established. Finally, for demonstrating the superiority of our new series over the Burnside’s formula and other classical or recently discovered asymptotic series, some numerical computations are provided.
