This symbol means that there is a high symmetry axis 3-fold) perpendicular to the plane of the window and mirror planes of symmetry going through the main axis that ‘reflect’ the motif (7) right-left. In this case, like in most 3-folded patterns the motif extends along above and below the horizontal line, thus filling the plane by triplication (3-fold) and reflection (right-left). There is only one kind of mirror triplicated by the 3-fold axis thus 3m (or C3v).
