Indeed - it seems to me that as stated, the thing _is_ a
(non trivial) translation - I reckon there is something
clockwise in the question (as stated) that should be
counter clockwise ('cos when I change it, it does work).
(for fun: what happens when you replace the triangle by a polygon,
and the order of rotations by some permutation of the order?)
