• Indecomposable Representations Of Order Of E6 

      Omar, A. A. H [عبد الرؤوف عمر]; Sidky, F. I. ( Qatar University , 1985 , Article)
      The extended Dynkin diagram is a valued graph. We are going to construct a Baechstrom order A associateed to Eg. We prove, by constructions, that the order A of infinite lattice-type but can be listed (tame-type), i.e., ...
    • The Superimprimitive Subgroups Of The Alternating Group Of Degree 8 

      Omar, A. A. H [عبد الرؤوف عمر]; Kamal, E. M. ( Qatar University , 1984 , Article)
      A transitive permutation group G is called superimprimitive if it is imprimitive with non-trivial block systems of imprimitivity of lengths all the non-trivial divisors of the degree of G; The superimprimitivity concepts ...
