| Sep 24, 2022 at 2:14 | comment | added | Alec Rhea | @SimonHenry Thank you, I wasn't necessarily offended but the new version of the post is perfectly palatable. I don't see where in the question I claimed to have a limit stage definition, but I can understand how me writing out the limit symbol could be interpreted that way and I should have been more explicit about the role the limit stage played in my question. | |

I however hope you realise that the problem here is that you said in your question that you know how to define this construction at limit stage when this is in fact probably impossible. If you had said from the start that you were hoping for us to find a good way to define the construction I wouldn't have started by explaining to you why the most natural way to interpret your question doesn't work, and wouldn't have lost as much time on this... | |

| Sep 22, 2022 at 21:58 | comment | added | fosco | You might be interested in the notion of a ncatlab.org/nlab/show/small+presheaf small presheaf. I have no idea, however, whether the sequence $C, PC,PPC,...$ where $P$ is the small presheaf construction, is of any practical interest or whether it stabilizes. | |
