Summary
A formula defining a polycross pattern is introduced. The pattern appears to be a special latin square in which every clone has any one other clone as a neighbour and just once in each of the four directions North, South, East, and West, presenting an ideal polycross pattern. The formula holds good for n clones when n+1 is a prime.
