This is closely linked to the Pauli exclusion principle.
What does a particle even mean, right? Especially in quantum field theory, where two electrons are just vibrations of a single electron field.
Another issue is that if we consider magnetism, things only make sense if we add special relativity, since Maxwell's equations require special relativity, so a non approximate solution for this will necessarily require full quantum electrodynamics.
As mentioned at lecture 1 youtube.com/watch?video=H3AFzbrqH68&t=555, relativistic quantum mechanical theories like the Dirac equation and Klein-Gordon equation make no sense for a "single particle": they must imply that particles can pop in out of existence.

Unlike the quaternions, it is non-associative.
The following things come to mind when you look into research in this area, especially the search for BB(5) which was hard but doable:
- it is largely recreational mathematics, i.e. done by non-professionals, a bit like the aperiodic tiling. Humbly, they tend to call their results lemmas
- complex structure emerges from simple rules, leading to a complex classification with a few edge cases, much like the classification of finite simple groups
Bibliography:
The very first chapter opens with Grand Commander Hou disrespecting spirits by opening up a sealed tomb and unintentionally releasing 108 demons who presumably reincarnate as humans, a backstory to the events that follow years later.
This is well shown in the Japanese The Water Margin, but is skipped in the Chinese The Water Margin unfortunately.
Actually, now that Ciro Santilli thinks about it, these were already likely meant as a "collectible" element by the author of the original book, as is strongly suggested by all the little illustrations of each character present on the Wikipedia page. Just like e.g. Catholic saints. It's Pokemon, but 2000 years earlier.
Ciro would notably feel many years later, that as he met random people online who were interested in improving eduction, or was otherwise networking to reach his goals, as if he were actually building up his 108 stars of destiny.
A central part, and perhaps the most interesting part of the novel, is how each character has been motivated by injustice to join the rebellion. This reminds Ciro of Final Fantasy VI
