Check composition for every g,h,x.The same formula follows from(gh)^-1=h^-1g^-1 and associativity;check identity separately.Listing an action table alone would not prove its axioms.

Conditions: none

Identity gives reflexivity,inverses symmetry and products transitivity,so complete orbits are equal or disjoint and cover G.Source family sorting does not make classes cosets;no centralizer/class-size formula or class equation is introduced.

Conditions: none

Right multiplying gxg^-1=x by g yields gx=xg,so singleton is equivalent to all-g commutation.Other is actually outside the complete orbit,justifying nonconjugacy without declaring every class singleton.
