- I am looking for any reference on the following Cayley's theorem:
-
- "a line such that two points C and D on this line are constrained to lie on curves
- of degree nc, nd and of circularity pc, pd, the curves not lying in parallel
- planes, generates a ruled surface of degree nc(nd-pd)+nd(nc-pc)"
-
- I am especially interested in the exception case where the curves
- lie in parallel planes.
