Roice Method
This method is the 4D version of the "ultimate solution for the rubik's cube's.
check it out here: [1]
Notation and 2-gen "3^3" moves
Notation is similar to that of the 3^3. There are 8 cells, UDFBRL and AK, with K being the hidden (nearer) cell and A the farther cell.
Each cell has 6 ways to rotate, UDFBRL.
The cell to be rotated is first stated, followed by the rotation. ex. RR,AF,RR,AF',RR'. For general moves, use - (for blank, this is used for writing move subsets)
<RR,A-> moves mean to only use RR and A moves. This method is used by Matthew Sheerin.

Sheerin-Zhao Method (Hybrid)
This method is an attempt to make a 4D analogue of the Friedrich, or CFOP method. Using this method results in around 650 to 900 moves, even if no shortcut turns are used. This method needs significant improvement because of the move count required for the last layer.
Prerequisites
- Knowledge of how the cube rotates.
- The Friedrich Method (F2L/OLL/PLL). 2-look OLL/PLL is enough.
Summary of the Method
- Cross: Make a cross by solving 8 2C pieces on the far cell.
- F2L: Fill in F2L slots by joining F2L pairs (2C/3C) together and inserting them into their respective slots.
- S2L: Fill in S2L slots. This is done by moving a 3C piece and its respective 4C piece onto the farthest cell (i.e. the last layer). Then, OLL algorithms are used to orient the pieces so that they can be joined using <RR, A-> moves. They are then inserted by using more <RR, A-> moves.
- OLL: Orient the LL 2C pieces, then the 3C pieces, using OLL-C (corner OLL) algorithms, such as the sune/antisune. Try to get as many corners oriented as possible as well. Setup moves are highly recommended here.
- Pre-PLL: Permute the 2C of the LL using U-perms.
- PLL: Solve the LL like a 3^3 by using <RR,A-> moves.
- Parity: If the "top face" of the LL is 180 degrees off from the rest of the puzzle, use the <RR,A-> variant of the supercube centers algorithm (R U R' U five times)
