    Harry Gindi points out that “infinity-field” redirects here, clashing with the unrelated entry of the same name.

    I can’t fix it right now. Maybe later.

  2. Fixed on this page (was a relic of the unicode issues). The pages where infinity-field is used will need re-rendering, I will do that programatically in a second.

    Only two pages needed re-rendering it seems, done now. [Edit: actually there were a few more, but should be done now. There was a similar problem at λ-ring, which also should be fixed now along with references to it.]

    Should this page have redirects from ’delta-ring’ etc.? If so, we need disambigution with the Buium-Borger sense.

    There’s already a redirect for delta-ring and delta-rings, but not for δ\delta-ring or δ\delta-rings. (There are a bunch of repetitions in the redirects; I imagine whoever it was (Toby?) was working quickly and copy-pasted σ\sigma too many times.)

    I meant to ask whether people use this term, but a quick look shows they do wikipedia: delta ring.

    So I guess disambiguation is needed to distinguish this from the other.

    Added a small disambiguating note, but really we should strip redirects, set up a disambiguation page, etc. No time at present.

    Despite the announcement in comment #8 being a duplicate of that in comment #7 (?), I see from the edit history that #8 in fact fixed two little typos.

    While looking into this, I have slightly rearranged the first parenthetical in the sentence on empty families (here) to make it clearer what “both” is referring to.

    I am dubbing the other notion of δ\delta-ring with the name “Joyal δ\delta-ring”, and will create an article soon.
