OD-Characterization of the Symmetric Group S₂₈

Abstract

It is proved that the symmetric group S28 is characterized by its order and degree pattern. In fact, S28 is 3-fold OD-characterizable.

OD-Characterization of Symmetric Group S57

“…In a series of articles ( Ref.to [2]- [17]), it was shown that many finite almost simple groups are OD-characterizable [see [2] Definition 1.1 and 1.2]. For convenience, we point out some of these results in the following proposition 1.…”
