Abstract

For an odd positive integer n, we determine formulas for the number of irreducible polynomials of degree n over GF(2) in which the coefficients of x^n^-^1, x^n^-^2 and x^n^-^3 are specified in advance. Formulas for the number of elements in GF(2^n) with the first three traces specified are also given.
