Clara is a fashion designer. She is designing a pattern for a shirt fabric. The design is made up of small squares. There is a decorative pattern

against one or more sides of each small square. The small squares will be

arranged in a block of four that will be repeated to make the larger overall

design. Within the block of four, there will be: - one square containing one

pattern - one square containing two patterns - one square containing

three patterns - one square containing four patterns. One possible way of

arranging the designs in each of the small squares is shown below. What is

the total number of different small squares that can be created? *
