There are, up to isomorphism, two possibilities for a group of order 121. Both of these are abelian groups and, in particular are abelian of prime power order.
The classification follows from the classification of groups of prime-square order.
See also groups of prime-square order for side-by-side comparison with the situation for other primes.
The groups are:
| Group | GAP ID (second part) | Defining feature |
|---|---|---|
| cyclic group:Z121 | 1 | unique cyclic group of order 121 |
| elementary abelian group:E121 | 2 | unique elementary abelian group of order 121; also a direct product of two copies of cyclic group:Z11. |
