Add some traits of S18

[Moniker1998]

For now its a draft because the amount of properties that need to be added is a little overwhelming to me

[prabau]

If it's overwhelming, PLEASE do not do a gigantic PR. It's preferable to do several smaller PRs, each adding a subset of the properties. This will allow speedier review and merging. If one depends on another, even better is to wait until the previous one is merged. This will go quickly if each is of manageable size.

All of those changes will be me citing "this is a Komogorov quotient os S17 and S17 is ...", but it still requires me to search for those properties. That's why its overwhelming. The PR won't actually be that large/unmanageable

Other properties I'll be adding in a separate PR (or PRs)

@prabau I've tried updating my branch (double-pointed-cocountable-topology-on-R) to be up to main, but it seems like it treats this PR like this huge update now. Do you know how to fix it? Should I close this and create new pull request?

@Moniker1998 Sorry I just saw this. I think the right way was to "merge main into your branch", but I am not quite sure how to do this. @StevenClontz ?

Exploring this now. I'm pretty good at avoiding weird Git merges personally, but not so great at fixing them when they go awry. Let me see.
