Faster reduction

Still reduction to a 3x3, but faster: Pochmann-style centers, two edge pairs at once, wide parity.

Start: Pochmann-style centers

Steps

  1. Lesson 1

    Pochmann-style centers

    Build half of each side center, then shoot pieces over from the top one by one. Faster than the elevator.

    3 cases

  2. Lesson 2

    Last two centers

    Seven cases for the last two neighboring centers, each with one short algorithm. Includes the fix for fully swapped centers.

    7 cases

  3. Lesson 3

    Faster edge pairing

    Store with U', pair two vertical edges at once and solve the diagonal last-two form. Also covers 3-2-2-2-3 pairing.

    6 cases

  4. Lesson 4

    Advanced parity

    Four wide OLL parity algorithms, two of which also fix PLL parity, and three PLL parity forms besides opposite edge pairs.
