We extend earlier work of Waldhausen which defines operations on the algebraic
$K$theory
of the onepoint space. For a connected simplicial abelian group
$X$ and symmetric
groups
${\Sigma}_{n}$, we define
operations
${\theta}^{n}:A\left(X\right)\to A\left(X\times B{\Sigma}_{n}\right)$ in the
algebraic
$K$theory
of spaces. We show that our operations can be given the structure of
${E}_{\infty}$maps.
Let
${\varphi}_{n}:A\left(X\times B{\Sigma}_{n}\right)\to A\left(X\times E{\Sigma}_{n}\right)\simeq A\left(X\right)$ be the
${\Sigma}_{n}$transfer.
We also develop an inductive procedure to compute the compositions
${\varphi}_{n}\circ {\theta}^{n}$, and
outline some applications.
