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:$2,1,1,4,1,1,6,1,1,\ldots$
