Subgrupos isotrópicos de F m \overline{3} m para las representaciones \Gamma_{4}^{+}, X_{3}^{+}y \Gamma_{4}^{+} \bigoplus X_{3}^{+}. Para cada subgrupo (H) se han representado el parámetro de orden (\eta); el sistema de inclinaciones en la notación de Glazer; los vectores de la base del subgrupo, expresados mediante los vectores de la base de F m \overline{3} m; y la posición del origen del subgrupo. Para los grupos C 2 / m, P \overline{1} y P 2_{1} / c, se ha utilizado un setting no convencional, que es más conveniente para la descripción de la estructura.
