Dicyclic character table
= Dicyclic character table
Four one-dimensional characters and $n-1$ two-dimensional characters exhaust a dicyclic group of order $4n$. In the two-dimensional rows, the values at $a^r$ are $2\cos(\pi jr/n)$ and those on the two noncyclic cosets are zero. The one-dimensional rows depend on whether $n$ is odd or even.
