Equivariant bordism classification of five-dimensional $(\mathbb{Z}_2)^3$-manifolds with isolated fixed points

Denote by $\mathcal{Z}_5((\mathbb{Z}_2)^3)$ the group, which is also a vector space over $\mathbb{Z}_2$, generated by equivariant unoriented bordism classes of all five-dimensional closed smooth manifolds with effective smooth $(\mathbb{Z}_2)^3$-actions fixing isolated points. We show that $\dim_{\mathbb{Z}_2} \mathcal{Z}_5((\mathbb{Z}_2)^3) = 77$ and determine a basis of $\mathcal{Z}_5((\mathbb{Z}_2)^3)$, each of which is explicitly chosen as the projectivization of a real vector bundle. Thus this gives a complete classification up to equivariant unoriented bordism of all five-dimensional closed smooth manifolds with effective smooth $(\mathbb{Z}_2)^3$-actions with isolated fixed points.
