Question: The Ramsey number R ( a , b ) is the smallest number n such that any 2 - coloring of Kn results in a

The Ramsey number R(a, b) is the smallest number n such that any 2-coloring of Kn
results in a monochromatic a-clique or a monochromatic b-clique. Show that R(2, n)=
n. Next compute R(2,2,2): the smallest Kn with a 3 coloring that has at least one
2-cliques in any three of the possible colors.
