White's starting array can be derived from its number N (0 ... 959) as follows:
'''a)''' Divide N by 4, yielding quotient N2 and remainder B1. Place a '''Bishop''' upon the
'''b)''' Divide N2 by 4 again, yielding quotient N3 and remainder B2. Place a second '''Bishop''' upon the dark square corresponding to B2 (0=a, 1=c, 2=e, 3=g).
Line 14 ⟶ 15:
'''c)''' Divide N3 by 6, yielding quotient N4 and remainder Q. Place the '''Queen''' according to Q, where 0 is the first free square starting from a, 1 is the second, etc.
'''d)''' N4 will be a single digit, 0 ... 9. Ignoring '''Bishops''' and '''Queen''', find the positions of two '''Knights''' within the remaining five spaces. Place the '''Knights''' according to its value by consulting the following '''N5N''' table:
