<P>1 什么是色向和?</P>
<P>2 在一个05年的帖子里.看到了一句:<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%CB%C4%BD%D7">四阶</SPAN>出现需要<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%B6%A5%B2%E3">顶层</SPAN>相临的棱块互换的情况</P>
<P> 只需要把第3层转过90度.就可以达到非扰动态了. 可是转过90度之后.怎么用<SPAN style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"><FONT color=#000000>三交换</FONT></SPAN><SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%BB%B9%D4%AD">还原</SPAN>?</P>
<P>3 忍大师的观点是捆绑<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%C4%A7%B7%BD">魔方</SPAN>比子阵<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%C4%A7%B7%BD">魔方</SPAN>要容易.那么如何计算捆绑<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%C4%A7%B7%BD">魔方</SPAN>的状态数?</P>
<P>4 这个是忍大师的的定义 <FONT color=#000000><SPAN style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA">环</SPAN><SPAN lang=EN-US style="FONT-SIZE: 10.5pt; FONT-FAMILY: 'Times New Roman'; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-fareast-font-family: 宋体">:</SPAN><SPAN style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA">参与一个循环位移的块的集合称为一个环</SPAN></FONT></P>
<P><FONT color=#000000><SPAN style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"> 一个循环位移.是不是指经过一次一定的<SPAN class=t_tag onclick=tagshow(event) href="tag.php?name=%B9%AB%CA%BD">公式</SPAN>之后.有几个块移动了.</SPAN></FONT></P>
<P><FONT color=#000000><SPAN style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-bidi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA"> N次之后魔方还原为基态.则那几个移动了的块的集合就成为一个环?</SPAN></FONT></P>
