Subgroup ($H$) information

Description:$C_2^4$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(32\)\(\medspace = 2^{5} \)
Exponent: \(2\)
Generators: $b^{2}, d^{2}eg, eg, g$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the center (hence characteristic, normal, abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), the commutator subgroup, the Frattini subgroup, the socle, stem, a $p$-group (hence elementary and hyperelementary), and rational.

Ambient group ($G$) information

Description: $C_2^6:D_4$
Order: \(512\)\(\medspace = 2^{9} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Nilpotency class:$2$
Derived length:$2$

The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metabelian, and rational.

Quotient group ($Q$) structure

Description: $C_2^5$
Order: \(32\)\(\medspace = 2^{5} \)
Exponent: \(2\)
Automorphism Group: $\GL(5,2)$, of order \(9999360\)\(\medspace = 2^{10} \cdot 3^{2} \cdot 5 \cdot 7 \cdot 31 \)
Outer Automorphisms: $\GL(5,2)$, of order \(9999360\)\(\medspace = 2^{10} \cdot 3^{2} \cdot 5 \cdot 7 \cdot 31 \)
Nilpotency class: $1$
Derived length: $1$

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

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_2^{15}.A_4.C_2^6.C_2$
$\operatorname{Aut}(H)$ $A_8$, of order \(20160\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \cdot 7 \)
$\card{W}$$1$
