Abstract: The $ \bmod \;p$ $ {v_1}$-periodic homotopy groups of a space $ X$ are defined by considering the homotopy classes of maps of a Moore space into $ X$ and then inverting the Adams self map. In this paper we compute the $ p$ $ {v_1}$-periodic homotopy groups of an odd dimensional sphere, localized at an odd prime. This is done by showing that these groups are isomorphic to the stable $ \bmod \;p$ $ {v_1}$-periodic homotopy groups of $ B\Sigma _p^{2(p - 1)n}$, the $ 2(p - 1)n$ skeleton of the classifying space for the symmetric group $ {\Sigma _p}$. There is a map $ {\Omega ^{2n + 1}}{S^{2n + 1}} \to {\Omega ^\infty }(J \wedge B\Sigma _p^{2(p - 1)n})$, where $ J$ is a spectrum constructed from connective $ K$-theory, and the image in homotopy is studied.
