Ooooh Sexy... Part 2

Logic Level 3

When solving a Rubik's Cube, a common algorithm in speedcubing is the "sexy move," in which the solver performs the moveset \(R D R' D' \).

By mistake, Trevor got the algorithm wrong & performs the move \(R D R' D \).

How many times will he have to perform this move starting in a solved state, before he returns to the solved state again?

\(\bullet\) If you think that he won't be able to complete the cube, then answer as \(0\)
