Hello,

Could anyone explain me how to do the following:
I have a long list of integer numbers in groups of four:

list= {{10,3,5,7},{4,6,8,9},{0,8,3,6}, ...... }

or its Flatten version.

How to write a fast function g[list] which does this:

g[list] =x^10*y^3*z^5*u^7 + x^4*y^6*z^8*u^9 + y^8*z^3*u^6+ ...

It should be done many times (say, 10^4-6) on lists with length > 1000, so taking parts is not a good idea.
How to use Map or similar ?
Thanks.
