That is not right. Z_4 includes {0,1,2,3}, but for GF(4), that is not correct.

Hi, all,

I am not quite understanding the concept of "a polynomial over Galois Field"? whether "over some field" means the coefficients of the polynomial should be in some field? For example, make 4x^2+5x+6 over GF(4). Whether this means the coefficients 4,5,6 should be changed in GF(4). Here, we should notice that GF(4) is not Z_4.

thank you.
