    "abstract": "It is shown that extending Osp(4/1) supergravity to quaternion co-ordinates\nto get HU(4/1) gives the standard model with 3 generations of fermions,\nU(1)xSU(2)xSU(3) bosons plus 2 gravitinos, 1 graviton, and nothing else. It is\nshown using the method of components that this is the largest supergravity\ntheory possible. Briefly, we look at how this relates to 16D M-Theory (which I\ncall Q-Theory). I hope others will be encouraged to work on this idea. This\npaper was replaced because it now includes conclusions on the fermionic sector\nsuch as the number of generations.",
