A group is a set of objects with a binary operator which has satisfy various conditions. Suppose G is a set of elements with a binary operation ⋆. Select each condition which is required for ( G , ⋆ ) to be an group:
For any elements f, g, and h in G, (f * g) * h = f * (g * h).

There exist an identity element e in G such that for all g in G, g * e = e * g = g.
For all elements g in G, there exists an element g-1 in G such that g * g-1 = g-1 * g = e.
For any elements f, g in G, f * g = g * f.
For any elements f, g in G, the element f * g is also in G.
