This is not my wheelhouse, and presumably were what I am about to suggest be right a million other people would have already pointed it out (not on lemmy necessarily, just in general). But aren’t all of those sides equal so the relationship between snake’s and any cube side’s length effectively (as we see it anyway) shrinks/grows as it moves around the hypercube.
To be honest I don’t even understand what the cartoon means by ‘two non-consecutive parts of its coils’ so I wouldn’t take my word for anything.
Non-white Welsh people are fine, as a rule.
