Query: Homology of holomorphs of free groups   The holomorph of a free group $F_n$ is the semidirect product $F_n \rtimes
Aut(F_n)$. Using the methods of Hatcher and Vogtmann, we derive stability
results and calculate the mod-$p$ homology of these holomorphs for odd primes
$p$ in dimensions 1 and 2, and their rational homology in dimensions 1 through
5. Calculations of the twisted (where $Aut(F_n)$ acts by first projecting to
$Gl_n(\Z)$ and then including in $Gl_n(\Q)$) homology $H_*(Aut(F_n); \Q^n)$
follow in corresponding dimensions.
