关于Jaco图$J_n（1），n \in \Bbb N边数的一个注记
A note on the number of edges of the Jaco Graph, $J_n(1), n \in \Bbb N
摘要：
Kok等人[3]介绍了Jaco图\emph{(order 1)}。希望作为一种特殊情况，能找到有限雅科图$J_n(1)$的边数的闭公式。然而，Ahlbach等人[1]中讨论的算法表明这可能是不可能的。寻找Jaco图$J_n(1), n \in \Bbb N$的边数的闭公式仍然是一个有趣的开放问题。在本说明中，我们提出了三种替代方案，\emph{formula}。
英文摘要：
Kok et.al. [3] introduced Jaco Graphs \emph{(order 1)}. It is hoped that as a special case, a closed formula can be found for the number of edges of a finite Jaco Graph $J_n(1)$. However, the algorithms discussed in Ahlbach et.al. [1] suggest this might not be possible. Finding a closed formula for the number of edges of a Jaco Graph $J_n(1), n \in \Bbb N$ remains an interesting open problem. In this note we present three alternative, \emph{formula}.
