Abstract
A context-free grammar GG over an alphabet AA is defined as a set of substitution rules that replace a letter in AA by a formal function over AA. The purpose of this paper is to show that some combinatorial arrays, such as the Catalan’s triangle, can be generated by context-free grammars in three variables.
