Am I thinking of a number?
Let us say I am, and the first number of which I am thinking is four.
The third number will be a number which is my favorite number.
And I'll hesitatingly call the second number The Culprit in this supposition: $$a=b \rightarrow \binom {(a+b)(a-b)} {(a-b)} = \binom {b}{(a-b)} \rightarrow 2a=b$$
Exciting, isn't it? That completes my first "set"
Now I move forward powerfully to my next "set," which is a single number that helps you color a map efficiently. That's the whole thing. One boring number!
Now I'll additionaly add another, third, final, ultimate, closing, concluding "set" that will terminate the end of all of the sets.
Digitally speaking, this last set is quite unimpressive.
It is, in fact, boring as hell to anyone who might be reading this, but it is very special to me.
Being consistent, it's again my favorite number, repeated six times. That is, it's a six-digit number with all six digits being the same.
As you surely can see, this results in something kind of magical, doesn't it?
Hint #1:
The sets have been determined by Powerful reasoning. Now, some Additional reasoning needs to take place.
Hint #2:
The tag says mathematics.
Hint #3:
So, we've found some numbers. And, using Mathematics, we might use those numbers in a number of ways. Perhaps these numbers together might form another number? Maybe you're feeling a bit numb from all of the numbers (bummer!), and, because you're a latecomer who realizes it's almost summer, you decide to slumber on a bed made from lumber, then POW, it all adds up to a new number!
You submit the answer, unencumbered, and treat yourself to a nice sandwich.
Perhaps cucumber?
Hint #4 (Hint #3 distilled):
• Number from set 1
POW
• Number from set 2
ADD
• Number from set 3
Hint #5:
If you've followed the thread of this question all the way to this point, you may be asking yourself, "How is that steganography?"
And you'd be right in asking that, because, up to this (final) step, there has been none. (Hint, hint!)
