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've been since expanded on, most notably by Richard Klitzing, either via direct request or by means of expanding general building rules, which therefore has resulted in the umbrella term official Bowers style acronym (OBSA) for shorthands in accordance to Bowers' original ones.

The general building principle is to start with the full name and reduce every bit (numbers, operators, the base object, etc.) into characters. Thereafter some vowels get reintroduced to make the OBSA readable/pronouncable. For example, "small rhombicuboctahedron" first becomes SRCO, and finally sirco.
