| Description: | $C_9^4.(C_2\times C_{12})$ |
| Order: | \(157464\)\(\medspace = 2^{3} \cdot 3^{9} \) |
| Index: | \(2\) |
| Exponent: | \(36\)\(\medspace = 2^{2} \cdot 3^{2} \) |
| Generators: |
$a^{9}c^{7}d^{6}f^{7}, bd^{8}e^{3}f^{8}, f^{3}, a^{6}bc^{8}d^{8}f, d^{3}e^{4}, c^{12}de^{6}f^{3}, d^{3}, a^{4}, e^{3}, c^{2}d^{4}e^{7}f, c^{6}d^{3}e^{3}f^{3}, e^{3}f^{7}$

| Derived length: | $2$ |
The subgroup is normal, maximal, nonabelian, and metabelian (hence solvable). Whether it is a direct factor, a semidirect factor, or monomial has not been computed.
Ambient group ($G$) information
| Description: | $C_9:D_9^3.C_6$ |
| Order: | \(314928\)\(\medspace = 2^{4} \cdot 3^{9} \) |
| Exponent: | \(36\)\(\medspace = 2^{2} \cdot 3^{2} \) |
| Derived length: | $3$ |
The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.
Quotient group ($Q$) structure
| Description: | $C_2$ |
| Order: | \(2\) |
| Exponent: | \(2\) |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
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 $W = N_G(H) / Z_G(H)$.
