Subgroup ($H$) information

Description:$C_7^2:D_{14}$
Order: \(1372\)\(\medspace = 2^{2} \cdot 7^{3} \)
Index: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(14\)\(\medspace = 2 \cdot 7 \)
Generators: $b^{3}, e^{6}f^{2}g^{10}, f^{2}g^{12}, cf^{7}g^{7}, g^{2}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group. Whether it is a direct factor or a semidirect factor has not been computed.

Ambient group ($G$) information

Description: $D_7^3.C_6^2:D_6$
Order: \(1185408\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 7^{3} \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$4$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

Quotient group ($Q$) structure

Description: $C_6^2:S_4$
Order: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $(C_2^3\times C_6).S_3^3$, of order \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \)
Outer Automorphisms: $S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length: $3$

The quotient is nonabelian and monomial (hence solvable).

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_7^3.C_2^4:\He_3.C_6.C_2^4$
$\operatorname{Aut}(H)$ $C_2\times C_7^3.C_6.\PSL(3,7).C_3$
$\card{W}$ not computed
