In a rectangular table of any size, write numbers from 1 to 99 (as English words). Numbers should be written successively, going from the end of the line to the start of the next line. Letters in rows and columns must not repeat. Maximize the number of digits in written numbers.
Example:
| F | I | V | E | O |
| N | E | F | O | R |
| T | Y | E | I | G |
| H | T | Y | S | I |
| X |
Answer key: first write down the number of columns in your table, and then all written numbers. For the example the answer would be: 5; 5,1,40,80,6. Best answer earns 8 points; each next answer will earn two points less.
| O | N | E | S | I | X | T |

| E | F | O | U | R | N | I |
| N | E | S | I | X | T | Y |
| F | O | U | R | T | E | N |
| S | I | X | T | Y | F | O |
| R | T | Y |
