  In this paper we survey various notions of anonymity and symmetry for finite
strategic-form games present in relevant literature, and discuss notions of
fairness; show that game bijections and game isomorphisms form groupoids;
introduce matchings as a convenient characterisation of strategy triviality;
and outline how to construct and partially order parameterised (symmetric)
games with examples that range all combinations of surveyed symmetry notions,
which when combined with other results in this paper gives the precise
relationship between the various symmetry notions.
