How the sledgehammer manages edges.

In "Basics" chapter, cubies were conveniently oriented. What if not so lucky?

1)   that is the 'sledgehammer' adopted in "Basics".




The three cases require the use of up to three different "sledgehammer", but the approach is always the same: move the 'cubie' so that at least one sticker goes towards the face of the same color, following the rules of the "sledgehammer".

The edges return to their original position every 3 iterations of the 'Sledgehammer'. Therefore

With regard to only the edges the 'Sledgehammer' is a cyclic algorithm and repeats every 3 iterations
