The significant discussion about the possible chaotic behavior of the mixma
ster cosmological model due to Cornish and Levin [N.J. Cornish, J.J. Levin,
Phys. Rev. Lett. 78 (1997) 998; Phys. Rev. D 55 (1997) 7489] is revisited.
We improve their method by correcting nontrivial oversights that make thei
r work inconclusive to precisely confirm their result: "The mixmaster unive
rse is indeed chaotic." (C) 2001 Elsevier Science B.V. All rights reserved.
