欢迎老顾 智力玩具的前辈

欢迎顾先生的加盟。

顾先生在86年时就设计了出四阶魔方，真令我佩服。我在国外一个魔方论坛里得知，也有一个老外独自设计出四阶之事，而且结构与球结构的四阶是一模一样的。天亮也是独自设计出６轴八面体等魔方。你们都是我佩服之人啊。

嗯，正四面体是多面体的一个极限了。但四轴再下去是三轴，就成了两极类魔方了。

这是老外四阶的资料：http://twistypuzzles.com/forum/viewtopic.php?t=3912

In 1989 I have made completely functioning 3x3x5 (16 years ago). It at me is till now. In 1999 I have made 4x4x4 because to get it at me there was no opportunity. Then there was a break in some years. Right now at me too NOT ENOUGH time, but I try to find it as unembodied ideas do not allow to sleep easy.

Hi Per,
At creation of my 4x4x4 (it was in1999, instead of in 1989) I nothing knew about the mechanism of a Master Rubiks cube. Therefore it was necessary to experiment and alter much. Also has borrowed it from me....... 6 months. The cube smoothly rotates, but the size is little bit more, than an original cube that is insufficiently convenient for hands. When I have arrived to America and have bought the original 4x4x4 cube, the first, that I have made - have disassembled it. Identity of mechanisms has pleasantly surprised me.

不知老顾设计出的四阶是什么样的结构？真想见识一下啊。[em24]

以下是引用爱因斯坦在2005-12-12 11:55:06的发言：

我来发表一下我的看法:

四阶魔方可以利用五阶魔方的轴型结构来设计制造.

论坛里就有利用三阶魔方的结构将三阶魔方改造成二阶的帖子.

五阶魔方改四阶魔方也是一样的道理.

理论上如果能设计出n阶魔方的结构,那么就可以由它来做外形改造做出n阶以下的所有阶魔方.

拿四阶改造成三阶,那么三阶就是球形结构了,这样太浪费而已.

你有这种见识真的很难得，其实不等阶魔方也可按这样的原理作出来的。

如4*4*5魔方的制作：http://bbs.mf8-china.com/dispbbs.asp?boardID=5&ID=1326&page=3

以下是引用老顾在2005-12-12 8:39:24的发言：

我玩魔方大概在81年,设计2阶与4阶在83年,

4阶的设计有2种不同的方案,为什么会搞2种

主要想方便生产厂家选择,----

4阶的一种,即9楼大烟头提供的球型结构,

另外一种,哪天跟天亮QQ语聊---请他替

我介绍.

我不会贴图,再说这么久图也找不到了.

我除了佩服还是佩服，老顾厉害啊

二阶魔方扩展的可能与我想的这种相似：http://bbs.mf8-china.com/dispbbs.asp?BoardID=5&replyID=342&id=342&skin=0

我也很想看一下老顾的设计图纸
