Query: Achromatic numbers of Kneser graphs   Complete colorings have the property that any two color classes has at least
an edge between them. Parameters such as the Grundy, achromatic and
pseudoachromatic numbers comes from complete colorings, with some additional
requirement. In this paper, we estimate these numbers in the Kneser graph
$K(n,k)$ for some values of $n$ and $k$. We give the exact value of the
achromatic number of $K(n,2)$.
