Crucial features are important for the identification of patterns. Great efforts have been devoted to discover the most distinctive features. This paper presents the ideas of splitting patterns into 4- or 6- parts, integration for recognition, and selection of crucial combinations. The crucial combinations are explored with particular reference to 26 handprinted letters of the English alphabet. This paper proposes a new and simple algorithm to perform the crucial combinations. Also, the largest confusion regions and algorithms for finding them are provided. The most useful crucial combinations and the largest confusion combinations are listed in this paper.
