   Format: MarkdownItexFixed 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.

   Format: MarkdownItexOnly 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.]

   Format: MarkdownItexShould this page have redirects from 'delta-ring' etc.? If so, we need disambigution with the Buium-Borger sense.

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

   Format: MarkdownItexI meant to ask whether people use this term, but a quick look shows they do [wikipedia: delta ring](https://en.wikipedia.org/wiki/Delta-ring). So I guess disambiguation is needed to distinguish this from [the other](/http://www-personal.umich.edu/~bhattb/teaching/prismatic-columbia/lecture2-delta-rings.pdf).
