Subgroup ($H$) information

Description:$C_{35}$
Order: \(35\)\(\medspace = 5 \cdot 7 \)
Index: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(35\)\(\medspace = 5 \cdot 7 \)
Generators: $bc^{28}, c^{5}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a semidirect factor, and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 5,7$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_5:D_{35}$
Order: \(350\)\(\medspace = 2 \cdot 5^{2} \cdot 7 \)
Exponent: \(70\)\(\medspace = 2 \cdot 5 \cdot 7 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Quotient group ($Q$) structure

Description: $D_5$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $F_5$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $-1$
Derived length: $2$

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

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_5^2:C_4.S_5\times F_7$
$\operatorname{Aut}(H)$ $C_2\times C_{12}$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times C_{12}$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3500\)\(\medspace = 2^{2} \cdot 5^{3} \cdot 7 \)
$W$$C_2$, of order \(2\)
