You can create subgroups within a group from the Layout window. A subgroup element is composed of other elements within the group. Subgroup elements retain their former position within the subgroup. If a subgroup is ungrouped, the elements are set back to the group el...

Mathematics - Group TheoryLet \\\({\\\sigma=\\\{ \\\pi_i \\\mid i\\\in I}\\\) and \\\({\\\pi_i\\\cap\\\pi_j=\\\emptyset}\\\) for all \\\({ieq j\\\}}\\\) be a partition of the set of all primes into mutually disjoint subsets. We consider subgroups that pe...
In this paper, we study properties of the greatest subgroup of a semigroup in a Γ-semigroup. We also introduce a relation G on a Γ-semigroup and show that the relation G and the Green’s relation H coincide in a special class of a Γ-semigroup. This is a preview of subscription...
The meaning of SUBGROUP is a subordinate group whose members usually share some common differential quality.

Suppose G is a group with |G|=35. Prove that if H is a subgroup of G with order 7, then H is a normal subgroup of G. Let G be a group and let H be a normal subgroup of G. Prove that, for all a in G, the order of Ha in G/H is a divisor of the orde...
