论文摘要
{\ em箭头}和{\ em钻石}是三角形网格上定义的两个层次结构cayley图。在其无向版本中，它们是同构的，仅定义了同一图的两个不同的表示。本文在面向和非导向的情况下给出了其直径的表达。它还显示抗焦点的完整分布。
{\em Arrowhead} and {\em diamond} are two hierarchical Cayley graphs defined on the triangular grid. In their undirected version, they are isomorphic and merely define two distinct representations of the same graph. This paper gives the expression of their diameter, in the oriented and non--oriented case. It also displays the full distribution of antipodals.
