This is pattern FKOQR 1-1-1-3. It is a 4-shape tessellation, though I have combined three of the shapes into one. I shaded the design in three colors.
Color and arrange four patches to make two 4-patch blocks as shown below.
Put the two four-patch blocks together as shown below.
Repeat the two 4-patch blocks to make the pattern.
