Please keep your comments on topic.

comment Does a four-variable analog of the Hall-Witt identity exist?
@ArthurFischer It was one of the original tags, since the post was originally about trying to formulate the question. Seemed fitting at the time.

@mathh Very interesting. Which country is that?

comment Symbol for “such that” (not in set)
@mathh I've never seen $1:a$ meaning $\frac{1}{a}$. Can you show me an example where that is used in the literature?

I doubt much can be said. Not much is known about $\mathcal{G}(n)$.

I appreciate the book recommendations, though. They look like some interesting reads, I might pick them up.

comment The maths required for an economics degree
@Brian You're taking my statement out of context. My point was that the mathematics required for an undergraduate degree in computer science is undoubtedly sufficient to prepare the OP to go back to school for economics. I was not implying that economics is a mathematically dull field. Measure theory, topology, and differential geometry are not prerequisites for the typical undergraduate (or graduate) economics program.

comment Does every group have a 'cyclization'?
Ahh, I see, I had the maps backwards. Good question!

comment Does every group have a 'cyclization'?
@Bryan Right, but what I'm saying is, doesn't the trivial homomorphism to the group of order $1$ satisfy the conditions you gave? Am I misunderstanding them?
