%N A106311 Possible positive values of the discriminant of irreducible monic integral 
               cubic polynomials.
%C A106311 These discriminants were found by examining all irreducible integral 
               cubic polynomials x^3+ax^2+bx+c for a,b,c in [ -30,30]. Closely related 
               to A006832, discriminants of totally real cubic fields.
