OD-Characterization of Simple K4-Groups
L Zhang, W Shi - Algebra Colloquium, 2009 - World Scientific
Let M≠ A10 be a simple K4-group. In this paper, we prove that if G is a finite group with the
same order and degree pattern as M, then G≅ M. Equivalently, all simple K4-groups except …

OD-characterization of certain finite groups having connected prime graphs
AR Moghaddamfar, AR Zokayi - Algebra Colloquium, 2010 - World Scientific
The degree pattern of a finite group G denoted by D (G) was introduced in [5]. We say that G
is k-fold OD-characterizable if there exist exactly k non-isomorphic finite groups having the …
