Fixed the statement about the generation/span of SU-bordism classes by CYs. Now it reads as follows:

The SU-bordism ring away from 2 is multiplicatively generated by Calabi-Yau manifolds.

There are Calabi-Yau manifolds of complex dimension $3$ and $4$ whose whose SU-bordism classes equal the generators $\pm y_6$ and $\pm y_8$ in Prop. \ref{SUBordismRingAwayFromTwo}.

Together with the K3 surface representing $- y_4$, this means that CYs span $\Omega^{SU}_{\leq 8}\big[ \tfrac{1}{2}\big]$.

Further adjustment. Should be correct now, but deserves to be expanded further.
