Summary
| Item | Value |
|---|---|
| degrees of irreducible representations over a splitting field | 1 maximum: 1, lcm: 1, number: 1, sum of squares: 1 |
| Schur index values of irreducible representations | 1 |
| condition for a field to be a splitting field | any field |
| smallest ring of realization of irreducible representations (characteristic zero) | -- ring of integers |
| smallest field of realization of irreducible representations (characteristic zero) |
Character table
The character table for characteristic zero is:
| Rep/Conj class | (identity element) |
|---|---|
| Trivial representation | 1 |
There is a canonical bijection between the conjugacy classes and the irreducible representations here (unlike for bigger, more complicated groups). Indeed, it is the only bijection possible.
