    I filled in content at n-truncated object of an (infinity,1)-category.

    to go with my discussion with David Roberts. I had planned to go further and also write the entry on Postnikov twoers, but got distracted all day.

    Apart from that I just added this link to Higher Topos Theory and did some editing there, added a table of contents, expanded the floating toc.

    To David:

    I am on the train now, offline. Will try to write the corresponding entry on n-connected objects in an (oo,1)-category/topos, from Lurie's section 6 or-what-is-it.

    I am hoping we can use that then to say precisely what "Whitehead tower in Lie oo-groupoids" is.

    tried to polish the entry n-truncated object of an (infinity,1)-category a bit. In particular I tried to work out better (and correctly) how n-truncation relates to categorical homotopy groups.

    Lots of room to polish/expand this further, but I need to run now.

    @ Urs #4:

    n-truncated object in an (infinity,1)-category

    This doesn’t seem to exist!

    I found it: n-truncated object of an (infinity,1)-category. Now there is a redirect.
