Subgroup ($H$) information
| Description: | $C_{76}.C_6$ |
| Order: | \(456\)\(\medspace = 2^{3} \cdot 3 \cdot 19 \) |
| Index: | \(4\)\(\medspace = 2^{2} \) |
| Exponent: | \(228\)\(\medspace = 2^{2} \cdot 3 \cdot 19 \) |
| Generators: |
$b^{12}, c^{2}, b^{8}, b^{18}, ac^{19}$
|
| Derived length: | $2$ |
The subgroup is characteristic (hence normal), nonabelian, and metacyclic (hence solvable, supersolvable, monomial, and metabelian).
Ambient group ($G$) information
| Description: | $C_{38}.(C_6\times D_4)$ |
| Order: | \(1824\)\(\medspace = 2^{5} \cdot 3 \cdot 19 \) |
| Exponent: | \(456\)\(\medspace = 2^{3} \cdot 3 \cdot 19 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.
Quotient group ($Q$) structure
| Description: | $C_2^2$ |
| Order: | \(4\)\(\medspace = 2^{2} \) |
| Exponent: | \(2\) |
| Automorphism Group: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| Outer Automorphisms: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{38}.C_{18}.C_2^4$ |
| $\operatorname{Aut}(H)$ | $S_4\times F_{19}$, of order \(8208\)\(\medspace = 2^{4} \cdot 3^{3} \cdot 19 \) |
| $\operatorname{res}(\operatorname{Aut}(G))$ | $D_4\times F_{19}$, of order \(2736\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 19 \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(4\)\(\medspace = 2^{2} \) |
| $W$ | $D_{38}:C_6$, of order \(456\)\(\medspace = 2^{3} \cdot 3 \cdot 19 \) |
