    Just abit of fun!!

    Find a 5 digit number that:
    · Has no two identical digits.
    · Has two digits that are perfect squares.
    · Has two digits that are prime.
    · Has one digit that is neither prime, or a perfect square.
    · That has the second digit six less than the fourth digit.
    · That has the last digit half of the third digit.
    · That has the first digit three greater than the last digit.
