This wallpaper pattern would be classified as 'pm,' as it doesn't have any rotation, there is vertical reflection, and glide reflection is not present in a line that is not a reflection line. Ignoring the single grey crate and bottom two upside-down crates on the right, either of which would break the pattern, this is a perfect example of how wallpaper patterning is utilised in everyday life.
