  In this article, we determine the explicit toric variety structure of
$\hl^{A_1(n)}(\CZ^n)$ for $n=4,5$, where $A_1(n)$ is the special diagonal group
of all order 2 elements. Through the toric data of $\hl^{A_1(n)}(\CZ^n)$, we
obtain certain toric crepant resolutions of $\CZ^n/A_1(n)$, and the different
crepant resolutions are connected by flops of $n$-folds for $n=4,5$.
