I updated the code in msdn forum,
I calculated from the end of file
Discover file 4550 takes a long time to run,
Assume it runs a whole day a file, 4550 days I guess need 12 years to finish
full combination if only run at home.
Hope Python sympy can be faster than cmaple in Amazon instance
--
Sorry my calculation is wrong, it should have around 14 billions of
combinations after using program to count.

Dealing with multigigabyte data streams is not over the top nowadays.

Even if it was, I don't think there was any guarantee
that the "official" strings representing those exceptions
would be interned.
You were supposed to use the provide
