Subgroup ($H$) information

Description:$C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Index: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(2\)
Generators: $b^{8}, c^{6}$ 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), stem, a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.

Ambient group ($G$) information

Description: $C_4.D_{48}$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_2\times D_{24}$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Automorphism Group: $S_3\times C_4.D_4^2$, of order \(1536\)\(\medspace = 2^{9} \cdot 3 \)
Outer Automorphisms: $C_2^3:D_4$, of order \(64\)\(\medspace = 2^{6} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

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_3:(C_2^3.C_2^6.C_2^4)$
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\card{W}$$1$
