The Balaban 10-cage
|Named after||A. T. Balaban|
In the mathematical field of graph theory, the Balaban 10-cage or Balaban (3,10)-cage is a 3-regular graph with 70 vertices and 105 edges named after A. T. Balaban. Published in 1972, It was the first (3,10)-cage discovered but is not unique.
The complete list of (3-10)-cage and the proof of minimality was given by O'Keefe and Wong. There exist 3 distinct (3-10)-cages, the other two being the Harries graph and the Harries–Wong graph. Moreover, the Harries–Wong graph and Harries graph are cospectral graphs.
