So, this is the summary of what I've learned with this thread (thx everyone!):
6 DIFFERENT 3-3s: Polina Shelepen (3T+3T, 3S+3T, 3F+3T, 3F+3Lo, 3Lz+3T, 3Lz+3Lo)
5 DIFFERENT 3-3s: none
4 DIFFERENT 3-3s: Surya Bonaly (3T+3T, 3S+3T, 3F+3T, 3Lz+3T); Elena Radionova (3Lz+3T, 3Lo+3T, 3S+3T and, according to AlexRus, 3T+3T)
3 DIFFERENT 3-3s: Midori Ito (3T+3T, 3Lz+3T, 3A+3T (maybe 3Lo+3Lo, if you remember when please post the link)); Irina Slutskaya (3S+3Lo, 3T+3T, 3lz+3Lo); Shizuka Arakawa (3Lz+3T, 3S+3T, 3S+3Lo); Adelina Sotnikova (3T+3T, 3Lz+3T, 3Lz+3Lo); Carolina Kostner (3T+3T, 3F+3T, 3Lz+3T); Yu-Na Kim (3T+3T, 3F+3T, 3Lz+3T).
I didn't count the 3-jumps combos nor Liza, because she has never landed a clean 3T+3T in competition, just 3S+3T and 3Lz+3T (please correct me if I'm wrong...)!
I've learned a lot of things...
