:formula_4In other words,:formula_5Thus the trace of "Sn" is given by:formula_6with the first few terms given by the sequence 1, 3, 9, 29, 99, 351, 1275, … .
:formula_4:formula_5Таким образом, след матрицы "Sn" равен:formula_6в зависимости от "n" образуя последовательность: 1, 3, 9, 29, 99, 351, 1275, … .
