Using the Luthar–Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of the integral group ring of the Suzuki sporadic simple group Suz. As a consequence, for this group we confirm the Kimmerle’s conjecture on prime graphs.

We study a self-dual N = 1 super vertex operator algebra, denoted A, and prove that the full symmetry group is Conway’s largest sporadic simple group Co1. We verify a uniqueness result for A which is analogous to that conjectured to characterize the Moonshine vertex operator algebra V . The action of Co1 on A is sufficiently transparent that one can derive explicit expressions for the McKay-Tho...

BACKGROUND Hereditary non polyposis colorectal cancer (HNPCC) appears to have a better prognosis than sporadic cancer. In the present study we evaluated the clinical outcomes of HNPCC patients with their sporadic colorectal cancer counterparts arising from the general population recorded in a population-based cancer registry in Iran. PATIENTS AND METHODS The population studied consisted of 12...

OBJECTIVES (1) To test the hypothesis that minor physical anomalies are increased in patients with schizophrenia and (2) to investigate differences in the prevalence of minor physical anomalies in patients with familial and sporadic schizophrenia and their first degree relatives. METHODS A weighted Waldrop assessment was carried out on 214 subjects in five groups: schizophrenic patients from ...

BACKGROUND Patients with hereditary non-poliposys colorectal cancer (HNPCC) have better prognosis than sporadic colorectal cancer (CRC). Aim of our retrospective study was to compare the overall survival between sporadic CRC and HNPCC patients. METHODS We analyzed a cohort of 40 (25 males and 15 females) HNPCC cases with a hospital consecutive series of 573 (312 males and 261 females) sporadi...

Let G be a finite group. We denote by Γ(G) the prime graph of G. Let S be a sporadic simple group. M. Hagie in (Hagie, M. (2003), The prime graph of a sporadic simple group, Comm. Algebra, 31: 44054424) determined finite groups G satisfying Γ(G) = Γ(S). In this paper we determine finite groups G such that Γ(G) = Γ(A) where A is an almost sporadic simple group, except Aut(McL) and Aut(J2).
