This is a special Daisy because you can make all the numbers from 1 to 35. You are only allowed to add neighbours (numbers touching each other) and you can only use one of each number in a sum. |

We can make all the numbers from 1 to 35 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 35.
