Abstract: For an unbranched covering $ f:{M^n} \to {N^n},[M] = (\deg f)[N]$ in unoriented cobordism $ {\mathfrak{N}_*}$. Thus, in general, if $ f:M \to N$ is a branched covering, then $ [M] - (\deg f)[N]$ depends upon the branching behavior.

In this note we describe the ideal $ {I_G}$ of unoriented cobordism classes $ [{M^n}] - \vert G\vert[{M^n}/G]$, where $ G$ is a finite group acting on $ M$ so that $ M \to M/G$ is a $ \vert G\vert$-fold smooth branched covering of closed smooth manifolds.
