Bowers style acronym

Bowers' acronyms are a shorthand notation created by Jonathan Bowers, used to identify polytopes without having to write their full (often quite long) names. They have been since expanded on, most notably by Richard Klitzing, either via direct request to the former or by means of expanding general building rules of him, which therefore has resulted in the umbrella term official Bowers style acronym (OBSA) for shorthands in accordance with Bowers's original ones.

The general building principle is to start with the full name and reduce every element (numbers, operators, the base object, etc.) into single characters. Then, vowels are added euphoniously to make the OBSA readable/pronouncable. For example, "small rhombicuboctahedron" first becomes SRCO, and finally sirco.
