Certain Applications of the Burnside Rings and Ghost Rings in the   Representation Theory of Finite Groups (II)
  Using the Burnside ring theoretic methods a new setting and a complete description of the Artin exponent $A(G)$ of finite $p$-groups was obtained in a previous article of the first-named author. In this paper, we compute $A(G)$ for any finite group $G$ -- hence providing the global version of that result.
