N(Factor)

One or more numbers representing the factorial design of the block. The cross product must match the number of lines of the block definition. If you specify more than one number, the numbers are used to produce an automatic trial coding in the result table by listing the factor level index in additional columns. The rightmost number runs the fastest. The order of trial specifications must match the factorial design. If you do not want to use this coding mechanism or if it cannot be applied, you may just specify one number which corresponds to the number of lines of the block definition.
