Gabriel Navarro最近提出的一个问题是，缺陷群的导出长度是否小于或等于块中不可约特征标的度数。在这篇文章中，我们为这一说法的有效性带来了新的证据。
A recent question of Gabriel Navarro asks whether it is true that the derived length of a defect group is less than or equal to the number of degrees of irreducible characters in a block. In this article, we bring new evidence towards the validity of this statement.
