I wrote a letter to Nana last night, my grandmother-in-law. And I included a small diagram of D8, the group of symmetries of a square.
I encouraged her to "look for patterns."
Poor woman... all she did was send me birthday money!!

Yes, it's a horrible torture for such a crime as sending money. We'll have to go visit her to set things straight. She'll probably feed us. I've always liked her.
Be careful sending such powerful mathematics to Nana. They, like cucumbers, might give her gas. :o)
