Hi

there is a mathematical description called complex four-vectors, that I would like to recommend.

That are ordered four-tupels and behave more like bi-quaternions than like vectors (hence I put them into the family of quaternions, too).

There reason for chosing this kind of mathematical representation are "aestetical" - meaning categories like simplicity, usability, elegance and power.

In this meaning I call that model "beautiful" and highly recommend to have a look.
