A Note on “Conjugacy Classes Outside a Normal Subgroup”

Abstract

In this article, we found a mistake in Theorem 3.6 in the article “Conjugacy classes outside a normal subgroup”, written by G. H. Qian, W. J. Shi, and X. Z. You, published in Communications in Algebra, 2004, 32(12):4809–4820. We correct it here.

Key Words:
