m ([1] Made the printable version retain the colors (you can choose the "simplified" printout to strip it down) [2] Removed the alg URLs from the printout by having the user now click on the SS cube logo to view the alg animations instead of the move length ordered pairs. [3] Removed the(unneeded) superscript arrows that usually appear with external links.)

The '''4Z4''' method is a 4x4 speedsolving method for [[ZZ method]] solvers. It starts off with a redux stage very similar to the [[Yau method]]'s, but it ends with a ZZ finish, giving the preferable method for ZZ solvers while retaining the advantages that Yau has. It is a definite improvement over other ZZ based 4x4 methods such as [[Z4]] and [[NS4]] due to a lower movecount and better ergonomics.

It is a definite improvement over other ZZ based 4x4 methods such as [[Z4]] and [[NS4]] due to a lower movecount and better ergonomics. It is also quite similar to the [[Mehtad]] method, although the way eo is done is more simple and has better recognition and the way to make the line is more simple.
  
 
Currently, there are no notable solvers with 4Z4 as it is quite a new method, as well as there being very few ZZ solvers who are fast at 4x4.
