The '''Human Thistlethwaite Algorithm''' (abbreviated to '''HTA''') is a human-usable version, proposed by [[Ryan Heise]], of the [[Thistlethwaite's algorithm]]. The solution is broken down into exactly the same basic steps of the computer Thistlethwaite algorithm, but each step in the human version is broken down into further sub-steps to make it managable for a human solver. The system proceeds as follows:

# Reduction to G₁ = &lt;U,D,L,R,F2,B2&gt;
#* [[Edge Orientation]]
# Reduction to G₂ = &lt;U,D,L2,R2,F2,B2&gt;
#* placement of U/D edges in U/D faces
#* [[Corner Orientation]], and placement
# Reduction to G₃ = [[Square group|&lt;U2,D2,L2,R2,F2,B2&gt;]]
#* Corners
#* Edges
# Final Solve <br/> Permutation of all pieces using only 180 degree faces turns
