Techniques: Min-Max

With this technology one relies on the fact that certain numbers arbitrarily small and large to become to be able. There is quasi a minimum and maximum border. If one must look for the description of the checksum 7 is the largest number the 4 if one 3 fields for the order has. If one e.g. of the 9 the minimum number to search wants (with 3 fields) draws one the next possible number those remainder from 3 exists off (2+1). That would be in this case the 6 and thus the minimum number the 1.
