Answer 1

the number of object in each group is known as set

Answer 2

Step-by-step explanation:

Each set G for which a group structure (G, m, u, −1) can be defined can be considered a group object in the category of sets. The map m is the group operation, the map e (whose domain is a singleton) picks out the identity element u of G, and the map inv assigns to every group element its inverse. eG : G → G is the map that sends every element of G to the identity element.
