Continuing our exploration of abstract Group Theory. I would like to start exploring the internal structure of a group: Subgroups, cosets, and conjugacy classes!

————-
I will also do a quick recap of my "improv" or "desert island" approach to exploring mathematics. This is a work in progress, and an experiment. I am hinting at a thesis that mathematics is a self-correcting code, where partially remembered or even mis-remembered axioms, definitions and theorems will converge to something equivalent to the "standard" accepted axioms, definitions, and theorems.
