“If we ended Part 1 proud of our accomplishment—
perhaps even a little smug—then we will get reacquainted
with our humility in this article.” — Robert Jacobson

Some related notes on algebra suggested by finite geometry:

Dynamic and algebraic compatibility of groups (1985 Dec. 11)

Groups related by a nontrivial identity (1985 Nov. 17)

Transformations over a bridge (1983 Aug. 16)

Group identity algebras (1983 Aug. 4)

I have no idea if any work has been done in this area since my own efforts in 1983-1985.
