Subgroup ($H$) information
| Description: | $C_1$ |
| Order: | $1$ |
| Index: | \(310\)\(\medspace = 2 \cdot 5 \cdot 31 \) |
| Exponent: | $1$ |
| Generators: | |
| Nilpotency class: | $0$ |
| Derived length: | $0$ |
The subgroup is the Frattini subgroup (hence characteristic and normal), a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), stem (hence central), a $p$-group (for every $p$), perfect, and rational.
Ambient group ($G$) information
| Description: | $C_{31}:C_{10}$ |
| Order: | \(310\)\(\medspace = 2 \cdot 5 \cdot 31 \) |
| Exponent: | \(310\)\(\medspace = 2 \cdot 5 \cdot 31 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 5$.
Quotient group ($Q$) structure
| Description: | $C_{31}:C_{10}$ |
| Order: | \(310\)\(\medspace = 2 \cdot 5 \cdot 31 \) |
| Exponent: | \(310\)\(\medspace = 2 \cdot 5 \cdot 31 \) |
| Automorphism Group: | $F_{31}$, of order \(930\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 31 \) |
| Outer Automorphisms: | $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
| 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 $p = 5$.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $F_{31}$, of order \(930\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 31 \) |
| $\operatorname{Aut}(H)$ | $C_1$, of order $1$ |
| $W$ | $C_1$, of order $1$ |
