摘要

在他的论文中，我们描述了一类受限的多多项式，称为脊凸多多项式。由两列创建的脊凸多角，使得列1(分别为column2)具有最多两个相邻的集合列序列，列2(分别为column1)具有至少一个相邻的集合列序列。此外，本研究还揭示了一种新的枚举脊凸多多项式的组合方法。

Number of Spinal-Convex Polyominoes

— : In his paper we describe a restricted class of polyominoes called spinal-convex polyominoes. Spinal-convex polyominoes created by two columns such that column 1 (respectively, column2) with at most two set columns sequence of adjacent ominoes and column 2 (respectively, column1) with at least one set column sequence of adjacent ominoes. In addition, this study reveals new combinatorial method of enumerating spinal-convex polyominoes .
