We can calculate the coefficients of the power series expansion of the primitive form inductively. By the theory of K. Saito and M. Saito, thus determined power series has a non empty range of convergence, but a experimental calculation strongly suggests that the range of convergence is bordered by the set defined by F_<1x>=F_<1y>=O., 紀要論文}, pages = {305--307}, title = {The Primitive Form of E^<12>}, year = {1987} }
