(based on 10 votes)

I am thinking of a whole number between 1 and 20, inclusive.
  • If my number is greater than the hypotenuse of a 30-60-90 triangle with a shortest side equal to 5, then it is less than 13.
  • If my number is smaller than the hypotenuse of a 45-45-90 triangle with a shortest side equal to 6, then it is greater than 7.
  • My number has only prime factors.
  • My number is not equal to 101 in base 3.
