Query: The eta invariant and the real connective K-theory of the classifying
  space for quaternion groups   We express the real connective $K$ theory groups of the quaternion QL group
of order $2^j\ge8$ in terms of the representation theory of by showing
$ko_{4k-1}(BQL)=KSp(S^{4k+3}/\tau QL)$ where $tau$ is any fixed point free
representation of QL in U(2k+2)
