For polynomials, the least deviating from zero in $L[-1,1]$ metrics with given number of leading coefficients, it is obtained the representation through the so-called extremal polynomials of the least deviation, whose number of sign changes is equal to their degree. The instruments of effective calculating of these polynomials are represented.
