The first solution: second layer

Per according to layer it must put the cube sottosopra. Hour we can take advantage of the fact to have left a cube to the empty angle for fastly posizionare three cubes to the chines of the median layer. There are two simple and symmetrical movements that will allow us to make ciò (it turns the cube like in figure if necessary): R U' R' and the U L.

R U' R'	L' U L

In this way can be posizionare three cubes to the chines of according to layer. Hour the cube would have to up appear così.

Rigiriamo of the cube with the side white man and posizioniamo the last cube to the angle left empty in the first layer. We proceed as we have made for the other cubes the angle but making attention not to remove nobody of the tre cubi to the spigoli posizionati ones well in according to layer. Hour we must use one of following the two algorithms (symmetrical): Of R' D R D F D' F' and D L Of D' the F' D F.

D' R' D R D F D' F'		D L Of D' the F' D F

Ora we have completed first due strati if all è gone bene.
