Generate unique 8 numbers combination from 8 arrays issue (slow)

[CFLam]

Eventually solved, implement this part with VC++, someone in C++ forum tell me to use the std::set structure for this issue

Well when I read that it's clear it's a simple permutation, or brute, however you want to look at it.

Sure there is an arraypermute function in udfs

Yes, its simple combination/permutation problem, major issues are speed and filtering.
