ON A GROUP EXTENSION INVOLVING THE SPORADIC JANKO GROUP \(J_{2}\)

Ural Mathematical Journal
Using the electronic Atlas of Wilson [21], the group J_2 has an absolutely irreducible module of dimension 6 over F_4. Therefor a split extension group of the form 4^6:J_2:= \bar{G} exists.

Pointed Hopf algebras over some sporadic simple groups [PDF]

Comptes Rendus. Mathématique, 2010
Any finite-dimensional complex pointed Hopf algebra with group of group-likes isomorphic to a sporadic group, with the possible exception of the Fischer group Fi22, the Baby Monster B and the Monster M, is a group algebra.

Integral group ring of the Suzuki sporadic simple group

Publicationes Mathematicae Debrecen, 2008
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.

ON THE CHARACTERISATION OF SPORADIC SIMPLE GROUPS BY CODEGREES

Bulletin of the Australian Mathematical Society, 2023
AbstractLetGbe a finite group and$\mathrm {Irr}(G)$the set of all irreducible complex characters ofG. Define the codegree of$\chi \in \mathrm {Irr}(G)$as$\mathrm {cod}(\chi ):={|G:\mathrm {ker}(\chi ) |}/{\chi (1)}$and denote by$\mathrm {cod}(G):=\{\mathrm {cod}(\chi ) \mid \chi \in \mathrm {Irr}(G)\}$the codegree set ofG. LetHbe one of the$26$sporadic

Tracking Motor Progression and Device‐Aided Therapy Eligibility in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterise the progression of motor symptoms and identify eligibility for device‐aided therapies in Parkinson's disease, using both the 5‐2‐1 criteria and a refined clinical definition, while examining differences across genetic subgroups.

Torsion units in integral group rings of Janko simple groups

, 2010
Using the Luthar--Passi method, we investigate the classical Zassenhaus conjecture for the normalized unit group of integral group rings of Janko sporadic simple groups. As a consequence, we obtain that the Gruenberg-Kegel graph of the Janko groups $J_1$,

Standard Generators for Sporadic Simple Groups

Journal of Algebra, 1996
Many results about sporadic simple groups are obtained by computer calculations. A common problem is to check and reproduce such results. The aim of the paper under review is to improve the reproducibility of computational results on sporadic groups.

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.
