that's cool never thought of before. there are an infinite number of similar examples and they are easy to construct. works like this consider an integer n. now call n! = k. now find k!. we know (k- 1)! = k!/k = k!/n!
that's it really or more generally (n!-1)! = (n!)!/n!
try it out it works
An example might be good...
22.214.171.124 = 24.
so if i include 126.96.36.199 in one series and exclude 24. Then in the other i include 24 but exclude 188.8.131.52
ie 184.108.40.206.9....23. 24 = 220.127.116.11.5.6....22.23
That makes sense.
In your is slightly different 6.5.4 = 18.104.22.168.1 because 4.6 = 22.214.171.124
we try 126.96.36.199.5 = 120 = 5.24
so 188.8.131.52.5.6.7.....23 = 184.108.40.206.9....23.24
i suppose there must be loads of ways to do this.
All very interesting though, I never really thought about that before.
