we just found this 2018 paper on our favorite research problem (obtuse triangular billiards) https://arxiv.org/abs/1808.06667
and, arrrgh,
they hit on important ideas! but also some parts are much messier than they need to be... and we know many improvements to their basic language and methods!... but we don't actually have any like, tangible theorems that would make our cache of weird specialist knowledge into a Paper... or any contacts who would care...
we need billiards friends
[monologues to her rats about how a "code sequence" is actually an element of the fundamental group of the double-triangle, via its projection from the free group on two generators, and it has a natural product operation which is _totally not_ the composition operation they're using in that paper and it makes it so much harder to parse, and reflects sadly that by even admitting she knows this much jargon she has become that which she hoped to destroy]
