MR Information

MR1------

Description:
Property: change the direction of the x-axis of the image to create a mirror image, and the symmetry is that a mirror image of a face is still a face
Source input: $a_{s}$
Source output: $Faces(a_{s})$
Follow-up input: $a_{f}$
Follow-up output: $Faces(a_{f})$
Input relation: $a_{f}$ is the flipped copy of $a_{s}$
Output relation: $Faces(a_{s})=Faces(a_{f})$
Pattern: symmetry, change direction
