The purpose of this note is to bring evidence to the fact that a certain automorphism of affine 3-space defined by N agata in [6] is not tarne. U sing the Bruhat decomposition at the level of the jacobian of the transformations involved and the product rules of double classes, we show that certain types of factorizations are impossible for this automorphism. I would like to thank F. Dumas and P. Polo for some useful discussions.
