Comment on ``Critical behavior of the chain--generating function of   self--avoiding walks on the Sierpinski gasket family: The Euclidean limit''
  We refute the claims made by Riera and Chalub [Phys.Rev.E {\bf 58}, 4001 (1998)] by demonstrating that they have not provided enough data (requisite in their series expansion method) to draw reliable conclusions about criticality of self-avoiding walks on the Sierpinski gasket family of fractals.
