-The square root of 163 occurs in several interesting pieces of mathematics.
-The function f(n) = n2 + n + 41 gives prime values for all values of n between 0 and 39, and for n < 107 approximately half of all values are prime. 163 appears as a result of solving f(n) = 0, which gives n = (-1+ \sqrt{-163} ) / 2.
