Abstract
A position code is applied on a surface to code positions in one or more directions. The code is based on a main number series which has the property that the place in the main number series of each number sequence of a first predetermined length is unambiguously determined. A position is determined based on one or more such number sequences of the first predetermined length. The orientation of the position code is discriminable from the main number series, but only for number sequences of a second predetermined length that exceeds the first predetermined length.
