审稿人意见In the revised paper new numerical justifications are given in Fig 2 from which we see that when $l$ increases some not-so-small projections appear in those bases in between the four corners Howe

感谢审稿人的意见。我们承认在描述中存在不准确之处。我们已经修改了文中的描述，在第6页的最后一段将“appear on the edges”更改为“appear between the four corners (although it cannot be strictly attached to the edges, it is not far from the edges)”。感谢审稿人的指正和建议。
