| Abstract: | By applying an algorithm, we get a representative set of the left cells and all the left cell graphs for the Weyl group W of type E 7,. From this, we see that the generalized r-invariants characterize all the non-exceptional left cells of W. We give a criterion to check the relation Ltilde] on the elements in the exceptional left cells of W. |
