When do limits and colimits of infinity-categories commute?
added some info on the case I'm interested in |

When do limits and colimits of infinity-categories commute?
@Adeel Thanks, but neither of these is quite what I need. I need index diagrams that are more complicated than just products (so 5.5.8.11 isn't enough), and 5.3.3.3 is only about limits/colimits in the category of spaces (I need the category of stable infty-categories). However, there is something about my case that's not that far from the category of spaces, and I'm editing the question accordingly. |

earlier statement was false. Salvaged it a little. |

Components of a Fiber Product
Sorry! The fact that $f|_{I^n_X}$ is the identity on the first $r$ coordinates doesn't imply that its image is $I^r\times U$. (@user52824, the incorrect arguments I gave are in fact local). |

Is there a finitely presented group with infinite homology over $\mathbb{Q}$?
Good to know. Thanks! |

@Alex: I thought any group homology of a finitely presented group is finite-dimensional. Are there examples where $H_2$ isn't? And yes, "infinite" means infinite-dimensional |

What is the coefficient ring of algebraic K theory of the discrete $\mathbb{C}$?
There are probably no modifications necessary in this case - thanks. And I'm interested in the torsion-free part, so fine with taking coefficients in any characteristic-zero field. Edited question accordingly. |

removed some parentheticals, added that only interested in torsion-free part |
