%T Epsilon-colorings of strips
%K
%X A special case of the Hadwiger -Nelson problem is to color a strip instead of the whole plane. The aim is to maximize the width of the strip such that it still permits a coloring with $c$ colors. We present a coloring that improves the recently best known value for 4 colors. This is discovered by considering colorings that satisfy slightly stronger distance conditions . Moreover , we can show under a sensible assumption that this value is best possible for the stronger version of the distance conditions .
