如图所示，根据哈布历法的第二层次。

如果有三个货币，就会产生

3个一级交易对，

如果有四个货币，就会产生

2个二级交易对， 2个一级交易对。

如果有五个货币，就会产生

1个三级交易对， 2个二级交易对， 2个一级交易对。

如果有6个货币，就会产生

1个四级交易对， 3个二级交易对， 2个一级交易对。

或者

3个三级交易对， 3个一级交易对。

这就是所谓的三生万物。

```
3 - 3，3*1
4 - 6，2*2 + 2*1
5 - 9，1*3 + 2*2 + 2*1
6 - 12，1*4 + 3*2 + 2*1 or 3*3 + 3*1
N - (N-2)*3， 1*（N-2）+（N-3）*2 + 2*1或者更加复杂的情况。
