In this work, we describe the Cohen-Macaulay space CM of twisted cubics parameterizing curves C together with a finite map i: C → ℙ3 that is generically a closed immersion and such that C has Hilbert polynomial p(t)=3t+1 with respect to i. We show that CM is irreducible, smooth and birational to one component of the Hilbert scheme of twisted cubics.
