# On April 11th, 2015, I am now on a 200-Day Streak :)

Some things about the number 200: The number appears in the Padovan sequence, preceded by 86, 114, 151 (it is the sum of the first two of these).

The sum of Euler's totient function φ(x) over the first twenty-five integers is 200.

200 is the smallest base 10 unprimeable number - it can not be turned into a prime number by changing just one of its digits to any other digit. It is also a Harshad number.

The number of NASCAR Cup Series races won by Richard Petty.
