Orientation
From Hard Drop Tetris Wiki
A tetromino's orientation, with regards to Tetris refers to the different ways that tetromino can exist after rotations.
Normally all the tetrominoes have a total of nineteen orientations, but probably to make things more symmetric, newer games add six orientations: two for S, Z, and I.
