If we rotate a two-sphere in R^3 so it stays centered about the origin then two points don't move.
If we rotate a three-sphere in R^4 while it stays centered about the origin can it be done so that all points move?
Does this have anything to do with the fact the S^3 is parallelizable while S^2 is not?
Thanks for any help!
