SUMMARY
In the discussion, participants analyze the relationship between the order of an element in a factor group G/K and the original group G. It is established that if Kg is an element in G/K with order n, then (Kg)^n = K implies that g^n is in the normal subgroup K. However, this does not guarantee that g has order n in G, as it only indicates that g^n is an element of K. The conclusion is that the order of an element in the factor group does not necessarily imply the same order in the original group.
