math

I'd probably provide a link to a 3d-print of the tile, and/or describe the vague shape without the precise measurements. Something like "the tile is shaped like an isometric view of a top-hat, with a bite taken out of the top left". To be honest, I don't think the diagrams are all that load-bearing for people who can see either - hard to parse, impossible to tell if they are honest, etc. That's why there's so many proofs. Finally, for the actual connections one could break it into an adjacency graph. Each tile a vertex, each flat face dual to an edge (labeled with which face), and specify them out.

All this said; I'm not an expert. Part of why I'm excited for the forum and wanted to share.

And there is no "the" way to accessibility, surely. It takes dozens of things, most small. I agree visual LLMs will/have been a nice tool.
