dc.descriptionWe show that the conditions defining total reflexivity for modules are independent. In particular, we construct a commutative Noetherian local ring $R$ and a reflexive $R$-module $M$ such that $\Ext^i_R(M,R)=0$ for all $i>0$, but $\Ext^i_R(M^*,R)\ne 0$ for all $i>0$.
dc.descriptionIn the previous version, Proposition 2.1 is incorrect, as stated. We added the assumption "Artinian" in the statement
