Restricted Growth StringFor a Set Partition of elements, the -character string in which each character gives theBlock ( , , ...) in which the corresponding element belongs is calledthe restricted growth string (or sometimes the Restricted Growth Function). For example, for the SetPartition , the restricted growth string would be 0122. If the Blocksare ``sorted'' so that , then the restricted growth string satisfies the Inequality
