Query: On two-dimensional continued fractions for the integer hyperbolic
  matrices with small norm   In this note we classify two-dimensional continued fractions for cubic
irrationalities constructed by matrices with not large norm ($|*| \le 6$). The
classification is based on the following new result: the class of matrices with
an irreducible characteristic polynomial over the field of rational numbers is
the class of matrices of frobenius type iff there exists an integer solution
for a certain equation with integer coefficients.
