## A. The points A, B, C, D, and E with J$_{1}$ = − 1 . 0 and J$_{2}$ = − 0 . 5 

Typical contour plot of ( h, 0 , l ) at the points A, B, C, D, and E in the ( J$_{2}$ , J$_{3}$ ) phase diagram are shown in Fig. 11. The point A ( J$_{3}$ = − 0 . 5) is in the phase with ( h = 0, k = 0, l = 1). The point B ( J$_{3}$ = -1.5) is in the helical phase with the a axis. The point C ( J$_{3}$ = − 2) is the phase boundary between the phase with ( h = 0 , k = 0 , l = 1) and the helical phase with the a axis. The points D ( J$_{3}$ = − 3 . 0) and E ( J$_{3}$ = − 4 . 0) are in the phase with ( h = 1 / 2 , k = 0 , l = 1 / 2). 

## B. The points F and G with J$_{1}$ = − 1 . 0 and J$_{2}$ = 1 . 5 . 

Typical contour plot of ( h, 0 , l ) at the points F and G in the ( J$_{2}$ , J$_{3}$ ) phase diagram are shown in Fig. 12. The point F ( J$_{3}$ = − 0 . 5) is in the phase with ( h = 0 , k = 0 , l = 1). The point G ( J$_{3}$ = − 1 . 5) is in the helical phase with the a axis.
