This group is a semidirect product . One of its presentations is:
Position in classifications
Get more information about groups of the same order at Groups of order 32#The list
| Type of classification | Position/number in classification |
|---|---|
| GAP ID | , i.e., among groups of order 32 |
| Hall-Senior number | 20 among groups of order 32 |
| Hall-Senior symbol |
Arithmetic functions
Want to compare and contrast arithmetic function values with other groups of the same order? Check out groups of order 32#Arithmetic functions
Group properties
| Property | Satisfied? | Explanation | Comment |
|---|---|---|---|
| group of prime power order | Yes | ||
| nilpotent group | Yes | prime power order implies nilpotent | |
| supersolvable group | Yes | via nilpotent: finite nilpotent implies supersolvable | |
| solvable group | Yes | via nilpotent: nilpotent implies solvable | |
| abelian group | No |
GAP implementation
Group ID
This finite group has order 32 and has ID 5 among the groups of order 32 in GAP's SmallGroup library. For context, there are groups of order 32. It can thus be defined using GAP's SmallGroup function as:
SmallGroup(32,5)
For instance, we can use the following assignment in GAP to create the group and name it :
gap> G := SmallGroup(32,5);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [32,5]
or just do:
IdGroup(G)
to have GAP output the group ID, that we can then compare to what we want.
