### Symmetry4Charity

I am trying to help Common Hope get a permanent presence on the UK Global Giving website which will allow UK donors to the charity to benefit from Gift Aid where tax is added to the donation.

Common Hope need to raise £1000 from 50 unique donors by the end of April. Common Hope is an educational charity supporting and empowering children and their families in Guatemala.

To help them reach their goal I have set up a Symmetry4Charity project to name symmetrical objects after people who donate to the site.

In exchange for a minimum donation of £10 to the charity, I will create and name a symmetrical object for you. Donations can be made at my fund-raising site. A clue to why this is my charity of choice can be found in Chapter 12: July of Finding Moonshine.

If you would like to give the group of symmetries as a birthday present or to celebrate an anniversary then email me details of the significant date and I will weave the date into the construction of the symmetry group. Please email me to alert me to the fact that you have left a donation. dusautoy@maths.ox.ac.uk

Stop Press Thanks to all those who donated, Common Hope achieved their target on 24th April and now have a permanent place on the UK Global Giving Website.

Here is a list of the groups created so far that have helped change the lives of children in Guatemala.
