I see your point, Joost...
...and it is a good one.

However, the analysis is rather nuanced... mine is a technical point...

I don't want to debate it too much, given that it would be improper to
delve into an unpublished solution here (given that SG actually has
active solvers), but I nevertheless claim there are 3 variants (and 3
solutions is probably the wrong wording).
