Subgroup ($H$) information

Description:$C_2^4$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
Exponent: \(2\)
Generators: $\langle(8,9), (10,11)(14,15), (6,7)(8,9), (8,9)(12,13)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_2^5:C_6\times A_5$
Order: \(11520\)\(\medspace = 2^{8} \cdot 3^{2} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

Quotient group ($Q$) structure

Description: $C_2^2\times \GL(2,4)$
Order: \(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Automorphism Group: $D_6\times S_5$, of order \(1440\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \)
Outer Automorphisms: $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $1$

The quotient is nonabelian, an A-group, and nonsolvable.

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)$$S_5\times C_2\wr C_2^2\times S_4$
$\operatorname{Aut}(H)$ $A_8$, of order \(20160\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \cdot 7 \)
$W$$C_3$, of order \(3\)
