If you have two triangulated functors $F,G$, you can compute the cohomology of $FG(-)$ in terms of the cohomology of $G(-)$ and the cohomology of $F(-)$, in terms of a ``Grothendieck spectral sequence''. e.g. if $F,G$ are right derived functors on derived categories. This just comes from the standard spectral sequence on filtered double complexes.
Question: Is there anything written about ``$\ge 3$ dimensional'' spectral sequences?
By this I mean something which computes the cohomology of e.g. $FGH(-)$ in terms of cohomologies of the constituent functors, or computes the cohomology of a triple complex with (two?) filtrations. I'm aware that in principle you could just apply the spectral sequence to $F,G$ then to $FG,H$, but I imagine that it might be cleaner to do it all in one go and it would be nice to have a reference.
