Each card displays one property from each of the four categories below:

Type: oval, diamond, squiggle
Number: one, two, three
Color: red, green, blue
Design: solid, striped, outlined

Thus, a card containing three red striped ovals shares no attributes with a card containing two purple solid diamonds. Not all of the attributes will necessarily be used in these puzzles.

Your task is to find sets of three cards (4 sets for #1, 6 sets for #2) that for each category are either all the same or all different. The letters exist only to help you answer.
