Subgroup ($H$) information

Description:$C_2^4:C_{48}$
Order: \(768\)\(\medspace = 2^{8} \cdot 3 \)
Index: $1$
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Generators: $\left(\begin{array}{rr} 17 & 16 \\ 16 & 1 \end{array}\right), \left(\begin{array}{rr} 1 & 16 \\ 16 & 1 \end{array}\right), \left(\begin{array}{rr} 29 & 24 \\ 8 & 21 \end{array}\right), \left(\begin{array}{rr} 9 & 16 \\ 16 & 25 \end{array}\right), \left(\begin{array}{rr} 15 & 16 \\ 16 & 31 \end{array}\right), \left(\begin{array}{rr} 3 & 21 \\ 7 & 28 \end{array}\right), \left(\begin{array}{rr} 17 & 0 \\ 16 & 17 \end{array}\right), \left(\begin{array}{rr} 17 & 0 \\ 0 & 17 \end{array}\right), \left(\begin{array}{rr} 7 & 14 \\ 26 & 13 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is the radical (hence characteristic, normal, and solvable), a direct factor, nonabelian, a Hall subgroup, monomial, metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_2^4:C_{48}$
Order: \(768\)\(\medspace = 2^{8} \cdot 3 \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_1$
Order: $1$
Exponent: $1$
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $0$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group (for every $p$), perfect, 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)$$C_2.C_2^6.D_6^2$
$\operatorname{Aut}(H)$ $C_2.C_2^6.D_6^2$
$W$$A_4$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
