Routon

In mathematics, the routon number system extends the complex numbers into 128 dimensions. The routons are also called the centumduodetrigintanions or 128-ions. The number system was named after Massachusetts Route 128. It is represented using the symbol ${\displaystyle \mathbb {U} }$, because ${\displaystyle \mathbb {R} }$ is already used for the real numbers.^[1]

The 256-dimensional voudons come after the routons.
