由于之前算法有瑕疵，导致结果有误。经修改，不考虑首尾限制的情况，得到的结果如下：
_ (length (ff 1))
...

不考虑首尾限制的结果:
      1. 2. 6.10. 22. 76. 364.1876. 8316
考虑首尾限制的结果:
      1, 1, 2, 4, 11, 38, 156, 788, 4158
我的结果      
      1, 1, 2, 4, 11, 38, 156, 788, 4158, 23384   
谢谢验证了 n=9 4158 的结果
希望你能验证 n=10  23384
甚至         n=20  ?

这些数字串还是互相有联系的。

说明。
第1列数=考虑首尾限制的结果=(首不是0)+(首是0)，(首不是0)×2+(首是0)×4=不考虑首尾限制的结果

如果能找到通项公式，一切都不是问题。
初步想了下，可以看成1到（2n+1）的一个排列，满足1跟n+2之间隔1个数，2跟n+3之间隔2个数……n跟（2n+1）之间隔n个数。
然后用(2n+1)!-不符合要求的，最后再去重。难点在于不符合要求的不是很好求，二是结果去重不像简单除以2那么容易。

如果不包含0。则
_ (defun ff (n)
(setq num (+ n n 1))

好,这个代码和结果都很重要,找到了王守恩题问题根源,请做下去,看看n能做到多大
这就是 王守恩在1#所说的 三十年前玩的原题  2n数2n个位置(朗福德配对问题,已经经研究的较为成熟)
王守恩在1#所说的改进,实质是放宽条件, 2n数2n+1个位置,多一个空位( "0")确保对任意n都有解,改得好
但是求解数难度较大,相信会成功的

你把所有对应的个数对出来吧。比如f(1)=1，f(2)=1……
lisp局限性和效率低，如果换其他高级语言，可获得更大n的结果。对于两位数（如10），可取对应的单节字符，如10=":"，11=";"，12="<"，13="="，14=">"。然后统计符合要求的个数。

找这样的 B 也可以，B=首尾没有0，中间必须有0，不去重。
1, 1, 2, 4, 11, 38, 156, 788,.......=B/2+A014552
通项不太好找，这串数长得太快了，当然我在找。
