4tega

4tega is the 4-dimensional equivalent of the Ortega Method on 2³. There are 2 main variants, as there is no perfect way to generalize this method to 4d.

Variant 1

Orient Both Cells

Start by orienting a single side, using either colour from that side or its opposite side. This can easily be done without RKT by using blockbuilding. Next, use 2⁴ OLC strategies to orient the other cell. Because the first cell isn’t solved, you don’t have to worry about messing it up, allowing you to save moves.

Separate colors

Separate the colors of the cells that are oriented, leaving you with 2 2³ solves.

Permute Both Cells

Solve the first cell like a 2³ without RKT, then solve the other cell like a 2³, but using RKT.

Variant 2

Orient Both Cells

Same as in Variant 1.

Separate colors

Same as in Variant 1.

Orient Both Layers of Both Cells

Use RKT to orient both layers of both cells, just like OBL in 3D Ortega. This can be done using the OCLL algorithms.

P4L/PBLBC

Permtue all 4 layers of both cells at once using algorithms. Some algorithms can be found here.
