This paper shows that the (abelian) "3-fermion" MTC obtains the full Clifford group by braiding alone, if you store information in the correct way. Their model works in (3+1) dimensions, fitting into the general "Walker-Wang" paradigm:

The fact that (3+1)-dimensional abelian anyonic theories can implement the Clifford group by braiding alone is not surprising. It is entirely within the expected Bravyi-Konig bound:

The paper is not very professionally written, but it seems to contain a lot of interesting ideas.
