Subgroup ($H$) information

Description:$C_5^2$
Order: \(25\)\(\medspace = 5^{2} \)
Index: \(800\)\(\medspace = 2^{5} \cdot 5^{2} \)
Exponent: \(5\)
Generators: $ce^{3}f^{2}, de^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $(C_5^3\times C_{10}).\OD_{16}$
Order: \(20000\)\(\medspace = 2^{5} \cdot 5^{4} \)
Exponent: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_5^4.C_4.C_2^3.C_2^5$
$\operatorname{Aut}(H)$ $\GL(2,5)$, of order \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
$W$$C_2$, of order \(2\)
