Query: Legendrian curves in $\mathbb C P^3$: cubics and curves on a quadric
  surface   We prove that the number of legendrian rational cubics in $\mathbb C P^3$
through three generic points and a line is three; also we classify all
legendrian curves on a quadric surface. Several computations are additionally
verified using Macaulay2 computer algebra system.
