Subgroup ($H$) information

Description:$C_{13}$
Order: \(13\)
Index: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(13\)
Generators: $c^{6}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the commutator subgroup (hence characteristic and normal), a semidirect factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $13$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.

Ambient group ($G$) information

Description: $C_{78}:C_4^2$
Order: \(1248\)\(\medspace = 2^{5} \cdot 3 \cdot 13 \)
Exponent: \(156\)\(\medspace = 2^{2} \cdot 3 \cdot 13 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2\times C_4\times C_{12}$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^7:S_4$, of order \(3072\)\(\medspace = 2^{10} \cdot 3 \)
Outer Automorphisms: $C_2^7:S_4$, of order \(3072\)\(\medspace = 2^{10} \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and elementary for $p = 2$ (hence hyperelementary).

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_{26}.(C_2^3\times C_6).C_2^4$
$\operatorname{Aut}(H)$ $C_{12}$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_{12}$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(1664\)\(\medspace = 2^{7} \cdot 13 \)
$W$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
