To solve that case on top, where you probably should be holding your
LL, try (M U)*3 U (M' U)*3 U.
To solve the orientation, moving around other edges, try (R U R' U')
M' (U R U' r).
To flip adjacent edges, leaving everything in place, try M U M' U2 (M
U)*3 U M' U M2. You could also try it from the opposite side, as M' U
is bound to be faster. I'm just too lazy to learn a new alg.
To flip adjacent edges, moving around other edges, use M U M' U2 M U M'.
