Subgroup ($H$) information

Description:$C_2^3.D_{10}$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Index: \(6\)\(\medspace = 2 \cdot 3 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $a, b^{4}, c^{9}, a^{2}, b^{10}c^{3}, c^{6}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{60}.C_4^2$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_6$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

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_5:(C_2^4.C_2^6.C_2)$
$\operatorname{Aut}(H)$ $F_5\times C_2^5:D_4$, of order \(5120\)\(\medspace = 2^{10} \cdot 5 \)
$\operatorname{res}(\operatorname{Aut}(G))$$D_{10}.C_2^6$, of order \(1280\)\(\medspace = 2^{8} \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8\)\(\medspace = 2^{3} \)
$W$$D_{20}$, of order \(40\)\(\medspace = 2^{3} \cdot 5 \)
