Transformation of an EGT Grammar: New Grammar, New Designs

True design with grammars lies in the creation of the grammar rules, not in the application of the rules to generate design alternatives. Existing grammars can be modified to describe new languages of designs [1-4]. Studying an epicyclic gear train graph grammar leads to purposeful relaxation of grammar rules and subsequent discovery of new designs. A revised new EGT grammar is presented, which is designed to generate a wider selection of valid EGTS.
