Think of a number between 99 and 999.
My number is 57
Consider the following:
the number is less than 500; true
57%3C500
the number is a perfect square; false, cannot be written in the form n%5E2 (last digit is 7, prime number whose divisors are 1 and itself)
it is a cube; false, cannot be written in the form n%5E3 (if we take 4^3 we will have 64 which is less then 57, and if we take 5^3 it will be 125 which is greater then 57)

the first and last digits of the number are 5, 7, or 9,
