I wasn't going to put the groups on the card, but I could do. Currently I have put the rotations etc.
Good news is that I will be handing in my dissertation this week and then I'll have plenty of time to work on it. =)
I've attached some examples for p2mm. If anyone on here knows the wallpaper groups I will probably like someone to check it in the future to make sure all the cards are the group they say they are.
