Why would a facility use room numbers $3233$, $53$, $61$, $\infty$, $10^{100}$, $1729$, $4$, $1.61803$, $3.14159$, $1.33333$, $\sqrt{-1}$, $0$, $1$? I was part of TCS Ignite training after my BSc graduation from July 2007 to October 2007. The training space had a numbering system for its rooms such as 
$$3233,\; 53,\; 61, \;\infty, \; 10^{100}, \; 1729, \;4, \; 1.6180, \;3.1415, \;1.3333, \; \sqrt{-1}, \;0, \;1$$ 
What do these numbers mean in our life? 
I had this question in mind during training. Before I ask this question to somebody, I happened to leave the organisation unexpectedly. 
Can someone please explain?
 A: To develop my comment, here are the main points about each of the numbers: (note that I'm not aware of how much you know about each of the numbers, so I don't know to what length I should tell about them. )


*

*$3233$ is one of the least-popular numbers on the list. The most interesting fact about is that it can be written as a sum of two squares in two different ways: $23^2 + 52^2 = 32^2 + 47^2 = 3233$. Also, it's the hypotenuse of 2 Pythagorean triples: $3233^2 = 1185^2 + 3008^2 = 2175^2 + 2392^2$

*$53$ is a prime number, and a Sophie Germain prime (since $2\times 53 + 1$ is also a prime). So also, not a very exciting number.

*$61$ is again a prime number, but it's also the exponent of a Mersenne prime $2^{61}-1$.

*$\infty$ is an immensely useful concept (NOT a number) in mathematics. It's a key tool in analysis and many other areas. Without it, we wouldn't have differential calculus and many other things.

*$10^{100}$ is a quite large number, and it has been named 'googol'. It's not very much used in mathematics, but it has a funny name and Google is a derivative of this word, I believe as a result of a typo.

*$1729$ is, in my opinion, the coolest number on the list. It can be associated with Srinivasa Ramanujan, a famous Indian mathematician. Read the Wikipedia page. $1729$ has been used in popular culture, in Futurama, for example.

*$1.6180$ is an approximation for the Golden Ratio $\phi$. It's another popular number, that has been used to describe even the concept of beauty. It's used in art, photography, and it can be found in nature ... 

*$3.1415$ needs no introduction, it's an approximation for $\pi$. The ratio between the diameter and circumference of a circle, it's a real rock star in mathematics.

*$1.333$ is an approximation for $\frac{4}{3}$. This is a tricky one and I find it difficult to say anything 'cool' about this number. Maybe the coolest thing about it can be that the volume of a sphere is equal to
$$
 V = \frac{4}{3} \pi r^3
$$
where $r$ is the radius of the sphere. But maybe that's about it ...

*$\sqrt{-1}$ is one form for the imaginary number $i$, which is another true rock star in mathematics, right up there with $\pi$. Students in school might be doubtful about this number at first, because it's not a 'real' number, but it's tremendously useful in mathematical analysis. Without it, many technologies would not exist, because for example signal processing uses $i$. MP3 music files wouldn't exist without $i$ ...

*$0$ and $1$ are the some of the real building blocks of mathematics. They are used so much that it's even hard to start describing how useful they are. But I will say this: The previously mentioned $\pi$ and $i$, together with $0$ and $1$, are used in the very beautiful result
$$
e^{i\pi }+ 1 = 0
$$
Strangely enough, $e\approx 2.71828$ was not mentioned, it's also a famous number.
A: *

*3233 is semiprime and a product of other two prime numbers in the list 53 & 61. 3233 is the biggest room in the facility and can accommodate 200 people. Rooms 53 & 61 can accommodate 100 people each. All other rooms are labs accommodating 24 people with computers. In RSA algorithm these three numbers 3233, 53, 61 can be used. 

*I think 4 signifies four color theorem of Graph Theory.

*As per the below book link 1.333 is called as pythagorean number derived from a pythagorean triple (4, 3, 5).

The above facility was designed by people who worked in various universities and organizations such as NSA of United States and returned to India after 20 years.
This facility Head name is Srinivasan Raman which resembles the Mathematician name Srinivasa Ramanujan. Often, I used to think this space was not created accidentally. It has a purpose behind that. This training space is full of knowledge.
But I was not lucky enough to continue working in this space. Sometimes I used to think about these numbers and figure out what they mean. I had idea about few numbers. But, I am not sure about the number 1.333 still.
