# The classification of subfactors with index at most $5 \frac{1}{4}$

@article{Afzaly2015TheCO, title={The classification of subfactors with index at most \$5 \frac\{1\}\{4\}\$}, author={Narjess Afzaly and Scott Morrison and David Penneys}, journal={arXiv: Operator Algebras}, year={2015} }

Subfactor standard invariants encode quantum symmetries. The small index subfactor classification program has been a rich source of interesting quantum symmetries. We give the complete classification of subfactor standard invariants to index $5\frac{1}{4}$, which includes $3+\sqrt{5}$, the first interesting composite index.
