<P>Dino Cube(Puzzler2.15中有)的动作和普通三阶魔方的很不同,但它的12个块蛮像三阶的12个棱块(见下图),不知道对于一个打乱的Dino能否参照三阶棱块的复原法(限于三阶的“绕角三棱块轮换”)来复原?</P>

<P>(昨天右下方一个魔方图颜色填错,现已更正。)</P>

对。1楼我没说清楚,我是说对一个打乱的Dino就当它的12个块是三阶的12个棱块。(三阶是可以做一串动作使三个“绕角”的棱块三轮换的,虽和Dino不同--三阶的极易翻色,也仍可纠正,让它们和Dino的效果一样。)刚才到Puzzler中试了一下,这样的思路,有了“参照”,复原Dino就容易些了。问题是,如果拿到的一个Dino是未知的非标准配色,又是打乱的,复原起来恐怕会走点弯路。不知事前能否判断出各对面色是哪些以及是如何布排的?

三阶棱簇有此奇特性质,角簇和中心块簇没有这种性质,是否意味者棱簇和角簇、中心块簇之间隐含着什么重大的区别?

<P>唉,我没看出棱簇和角簇区别背后的深层问题,只是感到两者的区别蛮有意思的。</P>
<P>&nbsp;</P>
<P>此外,原来四阶、五阶的棱块也有这种性质!不仅棱块,四阶、五阶的心块组也有!(五阶的中心块和三阶的一样,也没有。)</P>
<P>&nbsp;</P>
<P>从上面三阶、四阶和五阶棱块的情况看,相当于整个棱块簇的色向从原来的右手座标XYZ转换为左手座标-X-Y-Z,三个轴反向相当于仅仅一个轴反向,比如相当于X-YZ,就成为XYZ的镜像了。</P>
<P>&nbsp;</P>
<P>还有,从现象看,如果把三阶魔方的中心块盖子暂时拿掉,那么,面对一个打乱的魔方,根据棱块,最多只能判断谁和谁是对面色,而这三对对面色是如何布排的(比如,红绿白是顺时针布排还是逆时针布排呢),仅据棱块是无法判断的。据角块就既可以给出对面色信息,又可以得到三对对面色的布排信息。</P>
<P>&nbsp;</P>
<P>总之,这些现象的背后是否还有什么奥妙呢?</P>

<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>

原来明华所谓的镜像不是在魔方前面放一块镜子!我考,大师啊!你懂不懂什么叫镜像?!你又神经病发着了!

明华大师,你还是失踪吧,何苦在这里混骂声,你失踪了,外人会觉得魔方吧的水平有质的提高,真的,不信你就失踪一年,何苦走到哪里都被人骂得狗血淋头。

现在又弄出一个中心对称,一个中心块又如何转到它的对称位置?明华大师,求求你,饶了我们吧,大家还想像正常人一样多活几年,再陪你玩下去,大家就成神经病了,魔方吧的智力形象恐怕也变得不堪入目了,你走吧。

如果用唯棱魔方和Dino比会更像些。两种棱块具有相同的位置形状颜色,却按照不同的规律运动。显然唯棱魔方的棱块要全能一些,它们可以实现整数个两棱换,而Dino的只能实现整数个三棱换,相当于偶数个两棱换,所以可以用唯棱魔方模拟出Dino的所有状态,反之用Dino只能模拟出唯棱的偶状态,奇状态(如6#例子)则不行。

至于自镜像,一种情况是一个簇的每一个块都到镜像位置,同时自身发生镜像(21楼说对了一半,于理不当遭受后面连续四层楼的攻击),如三阶棱块,Dino棱块;另一种情况是每一个块都到镜像位置,同时两个两个块之间发生相互镜像,如四阶棱块以及四阶面块。
所以一个簇能自镜像的两个条件就是:1、能按要求换位;2、块本身或两个块之间是镜面对称的。
三阶角块可以镜像换位,但是自身不是镜面对称的,同时没有两个互相对称的角块,不能自镜像。
三阶面块是镜面对称的,但是受到变换规律限制,不能镜像换位,也不能自镜像。
