 Multiplication Table (Posted on 2006-07-07)
Imagine a multiplication table (like the one below, except it continues on forever):

```   1   2   3   4
+---+---+---+---+---
1| 1 | 2 | 3 | 4 |...
+---+---+---+---+---
2| 2 | 4 | 6 | 8 |...
+---+---+---+---+---
3| 3 | 6 | 9 | 12|...
+---+---+---+---+---
4| 4 | 8 | 12| 16|...
+---+---+---+---+---
|...|...|...|...|...
```

Find three of the same number in a straight line somewhere within the table. If this is not possible, show why not.

From your initial post, I thought the three 4's you were referring to are the 4 that is the product of the coefficients 2 and 2 and the two 4's that are of the coefficients themselves.  These three 4's are not exactly in a straight line due to the table spacing and font selection, but if each number, including the coefficients, were placed in the middle of equally sized squares, they would be.
