论文摘要
该方法是通过对3和4连接三角形的生成函数的奇异性分析，渐近分析，$ {{} _ 3F_2} $超几何序列的属性，以及Tutte在平面图上的枚举工作。
The approach is through a singularity analysis of generating functions for 3- and 4-connected triangulations, asymptotic analysis, properties of the ${{}_3F_2}$ hypergeometric series, and Tutte's enumerative work on planar maps and chromatic polynomials.
