So, all circles in the complex projective plane contain $[i,1,0]=[1,-i,0]$ and $[-i,1,0]=[1,i,0]$, and these are fixed by all rotations. Wild.
That answer I linked to called them the "cyclic points".
DogAteMy: I think I've mentioned this before, but you will find the book by Pedoe called Geometry: A Comprehensive Course very interesting.
