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 $\mathbb {U}$ , because $\mathbb {R}$ is already used for the real numbers.^[1]

The 256-dimensional voudons come after the routons.
