## Sudoku #39

Here's what David Wells has to say about the number 39 in The Penguin Dictionary of Curious and Interesting Numbers:

"This appears to be the first uninteresting number, which of course makes it an especially interesting number, because it is the smallest number to have the property of being uninteresting. It is therefore also the first number to be simultaneously interesting and uninteresting."

Sudoku puzzles use the numbers from one to nine, each of which is considered "interesting". The number one represents unity. Two is the only even prime number. Three is common in religion and mythology. For example, the trinity is an important concept to many Christians. Four is the maximum number of colors needed to color a map.

Five is the number of fingers on one hand. Five is especially interesting - Wells devotes nine pages to it! Six is the first "perfect number" since 6=1+2+3 and 6=1*2*3. Seven is the number of days in a week and the number of deadly sins. Eight is the second cube and the only cube that is one less than a square. Nine is the third square and the number of people on a baseball team.

Anyways, I hope you find todays Sudoku puzzle interesting!
