We have two unknown positive integers m and n, whose product is less than 100. There are two additional statement of facts available: 1. mn is divisible by six consecutive integers {j, j + 1, ..., j + 5} 2. m + n is a perfect square. Which of the two statements above, alone or in combination shall be sufficient to determine the numbers m and n?
