Abstract
BY applying an algorithm, we get a representative set of the left cell s and all the left cell graphs for the Weyl group W of type E-7. From this, we see that the generalized tau-invariants characterize all the non-exceptional left cells of W. We give a criterion to check the rela tion (L) over tilde On the elements in the exceptional left cells of W .
