Abstract
There exists a long discussion over the issue of whether minimal alphabet or maximal alphabet gives maximum schemata. The article generalizes the concept of schemata to dependency relation based ‘extended formae’. Further, it proves that theoretical maximum schemata could be achieved through an operator exploiting extended formae and using maximal alphabet. It shows that the previous conclusion of minimal alphabet giving maximum schemata is also true for some operators. It is known that maximum schemata is advantageous to achieve maximum implicit parallelism. The article raises a discussion over the requirement of availing maximum schemata by showing some disadvantages also. As a conclusion, it suggests to use an intermediate level alphabet for representation, balancing maximal alphabet to avail maximum schemata and minimal alphabet to overcome the disadvantages due to maximum schemata.
