Group information
Description: | $C_{2}^{2} \times C_{4} \times C_{40}$ |
Order: | \(640\)\(\medspace = 2^{7} \cdot 5 \) |
Exponent: | \(40\)\(\medspace = 2^{3} \cdot 5 \) |
Automorphism group: | Group of order \(786432\)\(\medspace = 2^{18} \cdot 3 \) |
Outer automorphisms: | Group of order \(786432\)\(\medspace = 2^{18} \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
This group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and elementary for $p = 2$ (hence hyperelementary). Whether it is metacyclic or rational has not been computed.
