Subgroup ($H$) information

Description:$C_2^5$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Exponent: \(2\)
Generators: $\langle(1,4)(2,15)(3,10)(5,8)(6,14)(7,13)(9,11)(12,16), (1,11)(2,7)(3,5)(4,9)(6,16) \!\cdots\! \rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, 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: $C_2^4:F_8:C_6$
Order: \(5376\)\(\medspace = 2^{8} \cdot 3 \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $F_8:C_3$
Order: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Exponent: \(42\)\(\medspace = 2 \cdot 3 \cdot 7 \)
Automorphism Group: $F_8:C_3$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Outer Automorphisms: $C_1$, of order $1$
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian, monomial (hence solvable), and an A-group.

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_2^4:F_8:C_6$, of order \(5376\)\(\medspace = 2^{8} \cdot 3 \cdot 7 \)
$\operatorname{Aut}(H)$ $\GL(5,2)$, of order \(9999360\)\(\medspace = 2^{10} \cdot 3^{2} \cdot 5 \cdot 7 \cdot 31 \)
$W$$F_8:C_3$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
