<P>第三层的棱块,假如是相临面颜色不同(请问 图1),可以用公式 "<SPAN lang=EN-US style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri','sans-serif'; mso-bidi-font-size: 11.0pt; mso-fareast-font-family: SimSun; 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>R ( U’2 R’ U’ )<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>R ( U’ R’ U’ )</FONT></SPAN>"</P>
<P>但是,假如是相对面颜色不同,可以用什么方法? ( 除了用 " <SPAN lang=EN-US style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri','sans-serif'; mso-bidi-font-size: 11.0pt; mso-fareast-font-family: SimSun; 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>R ( U’2 R’ U’ )<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>R ( U’ R’ U’ ) </FONT></SPAN>" 这条公式两次 )</P>

这个公式主要是翻角色的吧,跟棱块关系不大(移动了棱块应该属于副作用)

建好十字以后,主要是运用OLL21-27对角块,然后再用PLL复原

乌木整了一大堆PLL,强调对棱换,故意忽视了角的变化。我看楼主需要的就是:r2R'2Ur2R'2U2r2R'2Ur2R'2。

<P>哈,不是我不管角块,而是1楼的角块涂成灰色,按惯例就是表示不管角块。</P>
<P>&nbsp;</P>
<P>此外,你的r2R'2Ur2R'2U2r2R'2Ur2R'2是两个对棱互换,所以如果不管角块的话,要两个对棱互换,也可以简单地做U2即可;要不动角块的话,就可以做r2R'2Ur2R'2U2r2R'2Ur2R'2 。</P>
