题意：
给出N个正方形，每个正方形正面的四个角各有一种颜色，要求组成不同的正方体的方案数。两种方案视为相同，当且仅当一个正方体可以通过各种旋转得到另一个。（方向不同也算不同方案）
$6leq Nleq 400$
题解：
输出样例+puts("0")就可以得到40分的好成绩！
然后这是一道暴力题！
那么写个暴力就ok了！

本文到此结束！
以上是我的口胡。嗯，被这题的题解感动到语无伦次的后果。
但是题解实际上就是暴力。。。。。。注意到一个性质就是如果两个对面的正方形确定了，那么整个正方体就唯一确定了。由于n特别小，所以可以直接暴力枚举两个正方形，用map存储方案即可。注意正方形可以旋转，所以四个方向都要加入map中。
看起来很简单，但是场上只有myh过了。。。其他人大多是40$ ightarrow$_$ ightarrow$（打表出奇迹）
代码放过就不给啦！
