A = {2, 3, 4} 
B = {1, 2, 6}
Given two sets, find the union of the two sets.
The union of the two sets A and B is the set of all distinct elements present in both sets. In other words, it is a set containing all the elements of A and all the elements of B without any duplicates. 

So, the union of sets A and B is {1, 2, 3, 4, 6}.
