Suggested Solving Orders

Keyhole Method
1. Fix tips
2. Solve 2 adjacent edges and the 3 adjacent corners
3. Use keyhole to orient and solve remaining edges

Important Issues and Notes
In step 3, different ways of bringing the keyhole into the upper layer can be combined to flip edges.

Useful Algorithms
In step 3, three cycle edges: F+ U+ F- U-
