This is a full cube hybrid of "Little-j" and "Z-Tip" pieces from the Spiral Group of puzzles. I will provide eight hybrid cubes that use all twelve of the spiral group pieces. This is number five in that set of eight.
Spiral Group pieces combine in many ways to form 4x4x4 cubes. Eight total pieces are needed to make a cube. It's possible to make cubes with as many as eight different pieces, but pairs make the most common solutions. Check the compatibility chart below for which other pieces you might want to use.
G = Forms a cube with Good interlock
O = Forms a loose Or unstable cube
X = Can't make a cube without other pieces added
H = Assembles into two Half-cubes
This chart is for basic mix of four pieces of each kind. Note that the pieces are also matched with themselves.
