Mar 20, 2017 at 13:15 comment added user106191 Thanks. Yes this is exactly the question. I thought it would be easier stating it more generally, I'm sorry. The fact that $h(\kappa) = 0$ is shown in Lemma 4.3 of arxiv.org/abs/1504.06752v2, as H. Zare kindly pointed out to me (The more general Curtis conjecture is not known to be true). How do you think a factorization of $J$ will help? $\kappa$ is in $coker J$, so does not lift to $\pi_{14}O$... Do you think one might deduce something from Madsen's statement about $H_*(BSO)$ and $H_*(BSG)$? Thanks already!
