  We extend a previous bispectrum analysis of the COBE-DMR 4 year maps,
allowing for the presence of correlations between all possible angular scales.
We find that the non-Gaussian signal found earlier for bispectrum components
including adjacent modes does not extend to triplets of modes with larger
separations. Indeed for all separations $\Delta\ell >1$ we find that the
COBE-DMR data is very Gaussian. The implication seems to be that the previously
detected non-Gaussian scale-scale correlation falls off very quickly with mode
separation.
