  Taken by itself, the interference with the etaprime appears to strongly
affect the amplitude of the transition eta->3 pi. I point out that this effect
is fictitious and also occurs in the mass spectrum of the pseudoscalars. Chiral
symmetry implies that the same combination of effective coupling constants
which determines the small deviations from the Gell-Mann-Okubo formula also
specifies the symmetry breaking effects in the decay amplitude and thus ensures
that these are small.
