This Daisy is special because you can makeevery number from 1 to 25.You are only allowed to add neighbours (numbers touching each other) and you can only use each number once in a sum. |

We can make **all the numbers from 1 to 2****5** using this Daisy.

Can you do better than this with a different set of numbers?

The challenge is to find six numbers to go in the Daisy from which you can make all the numbers from 1 to a number bigger than 25.
