I asked the question and can answer it for those interested. There is an infinite series of numbers of the order (a)3 + (b)3 = (c)3 +(d)3 as follows for a = 1,2,3... 1,729 = (1)3 + (12)3 = (9)3+ (10)3 13,832 = (2)3 + (24)3 = (18)3 + (20)3 46,683 = (3)3 + (36)3 = (27)3 + (30)3 . . . . . . . . . . . . . . .Also, I found others not in the series such as 134,379=(12)3+(51)3 = (38)3 +(43)3 and I am curious as to whether this is a known number set.

There are 376740 such sets and you must think me crazy if you think I will list them all!
Ratioal numbers
To any set that contains it! It belongs to {-8}, or {-8, sqrt(2), pi, -3/7, 99.3}, or all whole numbers between -43 and 53, or multiples of 2, or integers, or rational numbers, or real numbers, or complex numbers, or square roots of 64 or fourth roots of 4096 etc.
The union is all the numbers in all the sets.

Three sets of two
there are 5 diffeerent sets Natural Numbers whole numbers integers rational numbers irrational numbers.
the answer is -1
sets
A null set. Although they could be sets of letters, sets of people, sets of animals, in fact sets of anything other than numbers.
The complex numbers.
Those are not sets of numbers. They're just numbers. And they're equal.
