Step 3

In step 3, we insert the last corner on the bottom, and simultaneously place the edges on the top. This is not so difficult to recognise, because the edges are already oriented. There are only 17 possibilities, and one of them is that step 3 is already done when you arrive.

It is possible to solve this step in more ways than I list here.
