Abstract:
We study perfect colorings of the Johnson graph in two colors. We give sufficient
conditions for a perfect coloring of the Johnson graph to be $k$-regular and present examples
of perfect colorings. The proof of the theorem is in many respects similar to the proof of the
result by Etzion and Schwartz [1] on $k$-regularity of perfect codes.
