Moving sofa problem (en.wikipedia.org)

I was hoping this would explain how the upper bound was derived, but citation [1] just listed it with its own citations, and citation [6] is a book that I'm not going to purchase.

I didn't realise that this was a real thing when I saw it in Douglas Adams "Dirk Gentlys Holistic Detective Agency" a number of years ago

Interesting. Oddly enough, I used to have this massive custom sofa which was a real PITA to move... could only fit in storage unit if stood up on a roller dolly and so on. I bet there'll soon be an app using CV/ML to figure out if a sofa will fit/which way to move it. ;)
