I did not think that this would work, my best friend showed me this website, and it does! Since that time, groups have arisen in almost every branch of mathematics. Use MathJax to format equations. If $K$ is not contained in $H$ then $\frac{|K|}{|K\cap H|} > 1$. MathJax reference. What does it mean when an egg splatters and the white is greenish-yellow? Since $|K|$ divides $|H|$ we know that $p$ divides $|H|$, so since $\rm{gcd}(|H|,|G/H|) =1$ we know that $p$ does not divide $|G/H|$. Thi is a pair of a subgroup with an index... @DonAntonio But only the trivial group has a unique such subgroup. search results for this author. In this century, a third stream has joined the other two: infinite (discrete) groups. Let $K$ be any subgroup of $G$ such that $|K|$ divides $|H|$.

How can I fill two or more adjacent spaces on a QO panel? Then $K\subseteq H$ (as a special case of this, if $|K| = |H|$ then $K =H$ and I think this might be what is asked). 2:54: Let $ G $ be a finite group, and let $H$ be a normal subgroup with $(H,[G:H])=1$.

Although permutations had been studied earlier, the theory of groups really began with Galois A811-1832) who demonstrated that polynomials are best understood by examining certain groups of permutations of their roots. How are Presidential candidates, who run for the party ticket in Primaries and Caucuses, shortlisted? Making statements based on opinion; back them up with references or personal experience. As stated, the question is a bit vague, and I am having trouble interpreting it in a way that makes it correct. Here is something that does hold and which might be what is being asked: Let $G$ be a finite group and $H$ a normal subgroup of $G$ with $\rm{gcd}(|H|,|G/H|) =1$.

Is it consistent to say "X is possible but false"? Product details. If $H\unlhd G$ with $(|H|,[G:H])=1$ then $H$ is the unique such subgroup in $G$. Could you clarify what is meant by "such"? It's easy that $HK$ is a subgroup of $G$, thus $|K| / |H\cap K|$ divides $|G|/|H|$.
