## Plucker curves: Questions on an exercise from a book of Gerd Fischer

In Fischer's book on plain algebraic curves there is an exercise in which it is claimed that for every $n$ at least $2$ there exists a Plucker curve of degree $n$. As a hint one should consider unions of certain quadrics and cubics.

But Plucker curves are by definition irreducible.

Does anybody know what is actually intended?

 Perhaps the hint was supposed to read "intersection." – Qiaochu Yuan Mar 19 2010 at 7:58
