Abstract
In a recent Letter we have shown how COBE-DMR maps may be used to disprove Gaussianity at a high confidence level. In this report we digress on a few issues closely related to this Letter. We present the general: formalism fo r surveying non-Gaussianity employed. We present a few more tests for syste matics. We wonder about the theoretical implications of our result.
