<P><STRONG>[猜想]</STRONG>上述现象的原因是不是在于:除了魔方结构所决定的其动作的基本特性外,也许还在于块的自身特性。</P>
<P>&nbsp;</P>
<P>任一棱块本身含有一个镜面对称的“剖面”;</P>
<P>&nbsp;</P>
<P>任一角块含有一个三次轴(绕轴转3×120°重复)--即整个魔方的体对角线之一,但角块不含镜像对称面;</P>
<P>&nbsp;</P>
<P>六个中心块的位置关系是个刚性整体(不妨设想为魔方的体心处的一个“色子”的六个色片向六个方向延伸直到魔方的表面,只不过每片色片可以随着魔方表层一起旋转而已),它也不含镜像对称面,却有4个三次轴,即整个魔方的4根体对角线。此外,还有3根四次轴--也不会引起中心块簇的自镜像。</P>
<P>&nbsp;</P>
<P>至于四阶的心块为何也有自镜像现象(有帖子提到,降阶法开始合并心块时错做成心块簇的镜像后,魔方就复原不了),我就不会解释了,请哪位指点指点。</P>
