# What is the most beautiful number and why?

This is a note inspired by one one Quora. I am very eager what you think about numbers. Share what you think when it comes to knowing about your favorite number and also give the reasons for it!

Eager to know about some of the special numbers and their properties! :)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

108

One hundred eight (or nine dozen) is an abundant number and a semiperfect number. It is a tetranacci number.

It is the hyperfactorial of 3 since it is of the form 1^1 * 2^2 * 3^3

108 is a number that is divisible by the value of its φ function, which is 36.

In Euclidean space, the interior angles of a regular pentagon measure 108 degrees each.

In base 10, it is a Harshad number and a self number

Hi, for me it is definitely LaTeX:$\e$ It comes up in so many places: The formula describing a chain hanging between two posts ("Kettenlinie" in German); or -- not quite sure about that -- certain distributions in statistics; or this one: The integer closest to LaTeX:$\frac{n!}{\e}$ gives you the number of fixpoint-free permutations of LaTeX:$n$ distinct things.

Hope I remember it correctly: The continued fraction expansion of e is \LaTeX:$2,1,1,4,1,1,6,1,1,\ldots$
