https://github.com/django/django/blob/bae053d497ba8a8de7e4f725973924bfb1885fd2/django/db/models/lookups.py#L361 – check the whole file.

There is also much older commit which might help, if you only want a static list: https://github.com/django/django/blob/d4e578d0f64971483ded49f9cae460ea174b5138/django/db/models/sql/constants.py#L11 but this one is not available for importing anymore.
