  We raise the question of the realizability of permutation modules in the
context of Kahn's realizability problem for abstract groups and the $G$-Moore
space problem. Specifically, given a finite group $G$, we consider a collection
$\{M_i\}_{i=1}^n$ of finitely generated $\Z G$-modules that admit a submodule
decomposition on which $G$ acts by permuting the summands. Then we prove the
existence of connected finite spaces $X$ that realize each $M_i$ as its $i$-th
homology, $G$ as its group of self-homotopy equivalences $\E(X)$, and the
action of $G$ on each $M_i$ as the action of $\E(X)$ on $H_i(X; \Z)$.
