That doesn’t seem right—to solve it via pure rotation, you would need to do up to 5 + 4 + 3 + 2 + 1 rotations, looking at each pair once, not 6!. Not at all unrealistic.
You are right on the match, good catch and thanks.
I do still think that working memory constraints make it unrealistic to think that it might be more efficient to perform up to 15 mental rotations than to use vitaliya’s tricks.
