Abstract
For the standard 27-dimensional representation V of the exceptional group G of type E6 we prove that (SL(V),G) is a Donkin pair if and only if the characteristic of a ground field is greater than 13. We also develop an elementary approach to describe submodule structure of any exterior power of V.
