I've left some comments mostly minor, I'm accepting this on the basis it demonstrates a pack + mmt4d + unpack is equivalent to a matmul, which is easily verifiable from the output.

If the purpose of this test is also for documentation I think it could be improved, particularly with some comments to clarify the packing, but additionally I think a simpler example with smaller shapes would be better.
