There's a problem with this update: the embedded sagecell code (see ShowGAPCode.js, currently used by the GroupInfo page) contains its own copy of jQuery, 3.3.1, which it uses to redefine the global symbol $ when it is loaded. Although I can imagine workarounds (Use two versions of jQuery at once? Make our own modified copy of embedded_sagecell, and maintain it?), I don't see any great benefit. Let's put it on hold.

Since GAP in SageCell has problems at present (not letting us send more than a certain number of characters, or it simply fails) the best solution later might be to create our own copy of embdded_sagecell.js. There was a time when I investigate how to fix the problem and came up with a solution that the SageCell folks didn't like and didn't want to use, but it's been long enough now that I forget what it was. Googling just now couldn't seem to find the relevant online discussion, or I'd cite it!
