which 2x2 CLL cases are mirrors?

Most of L can be mirrored with a U turn before execution. Anti-Sune and Sune are obviously mirrors of each other. T and U can be mirrored, but it only works on 2 cases. H can be mirrored, but a U2 does the same thing and is generally faster.

these letters mean little to me, also, i do not count something that can be done left and right handed with the same result as a mirror
 
If you can tell one case apart from one of its mirrors then you'll have to use a mirrored alg. And the other way around: if the case after mirroring still looks the same then you can still the same alg
