Abstract (in Japanese) (See Japanese page) 
(in English) We consider $K$-tuples that are composed of IDs that identify $K$D sequences where the number of IDs is $N$. An equivalence structure (ES) is defined as a set of $K$-tuples that identify $K$D sequences considered equivalent. Whether or not two $K$D sequences are equivalent is determined based on their continuous subsequences. Since the number of possible $K$-tuples taken from $N$ IDs is $_N {mathrm P}_K$, the comparisons cause combinatorial explosion along with the increase of $K$. In this paper, we show that a $K$D ES can be generated from a $(K - 1)$-D ES when we have an assumption that a $(K - 1)$-D ES is a superset of a set of $(K-1)$-tuples that are taken from a $K$D ES removing the $k$th ID of all the $K$-tuples. In addition, we show that we can obtain ES's successively increasing $K$ and reduce the number of tuples to consider.
