611. The problem is to find three different digits such that, in whatever order they are used to make a three-digit number, that number will not be divisible by:
3, 5, 7, 11, 13, or 17
Furthermore, since more than one solution is possible, we are looking for the three digits whose product is the greatest.
To ensure that there is no ambiguity, suppose the three digits are a, b, and c. Then, none of the numbers:
abc, acb, bac, bca, cab, and cba
will divide by 3, 5, 7, 11, 13, or 17
and also the product of a x b x c must be as large as possible.
612. The following 16 letters can be anagrammed into a five-word phrase meaning "everyone is in it together."

614. The new teacher thought she'd get the children to drink the milk at recess more cheerfully by offering cookies with it. A lot of the children had illnesses and were out, causing various numbers of children to be present each day. One day the teacher noted that if there were five fewer children the next day, they would each get two cookies more if she brought the same number she had that day. However, the absentee list was low the next day, and she had four more children instead of five fewer. This meant that each received one cookie less than each child had received the day before. How many cookies did the children get the second day?
