I think this highlights part of our disagreement!! Mathematically, these are never independent of each other: the order always matters if translate is involved (assuming there is more than one of the functions :)

[I exaggerate slightly: it also doesn't matter in some edge cases such as an identity like rotate(0). But if translate is in there, they are dependent. ]

You absolutely need to tell the treasure hunter whether to walk 20 paces then turn left, or turn left then walk 20 paces.
