    I have added also the statement of the two relative versions of the Serre spectral sequence (here). No details yet.

    added this pointer:

    and implementation in Lean is in

    and will add it also to spectral sequence and maybe elsewhere

    @Urs it should be Floris et. al. There is a list of participents:

    Participants Jeremy Avigad, Steve Awodey, Ulrik Buchholtz, Floris van Doorn, Clive Newstead, Egbert Rijke, Mike Shulman.

    Checking the contributors supports this fact too.

    I have added a detailed example computation (here) of

    H 4(S G,)(/|G|) H^4 \big( S^{\mathbb{H}} \!\sslash\! G, \, \mathbb{Z} \big) \;\; \simeq \;\; \mathbb{Z} \oplus (\mathbb{Z}/\left\vert G \right\vert)

    In your proof, where it says’

    we have for the given finite subgroup of SU(2) (by this Prop) that:

    do you mean to give H nH^n rather than H 4H^4? Otherwise I don’t know what the parameter nn on the RHS of the equation is meant to be.

    Thanks. Fixed the “4” to “nn”.
