To go the rest of the way and you need to use something other than rotations about the origin, ie something more than just the action of F2.
To go the rest of the way you still only use rotations, just not the rotations in F2.
The way I always did it was to use rotations about some fixed line that doesn’t go through 0.
We seem to be talking about different things, I’m talking about doubling the surface of the sphere. You’re talking about how to get the center once you’ve doubled the surface.
Ahh yes, you’re right.
