论文摘要
引入了属于1型和7型家族的凸五边形瓷砖的旋转对称瓷砖。其中包括带有两倍和四倍旋转对称性的螺旋砖。那些旋转的对称砖是连接的边缘到边缘，没有反射对称的轴。
Rotationally symmetric tilings by a convex pentagonal tile belonging to both the Type 1 and Type 7 families are introduced. Among them are spiral tilings with two- and four-fold rotational symmetry. Those rotationally symmetric tilings are connected edge-to-edge and have no axis of reflection symmetry.
