PURPOSE:To compress the occupying capacity of a memory by constituting the titled converter of n connection matrix list bodies obtained by extracting lines or rows having different arrangement of elements from a connection matrix list and registering the extracted lines or rows in each digit and n connection matrix list indexes indicating the positions of the elements in the bodies. CONSTITUTION:Each line in the connection matrix list divided into four rows is regarded as one record, the record is divided into an upper digit and a lower digit and an upper digit connection matrix list body registering only an upper digit different code having different arrangement of a bit string of the upper digits and a lower digit connection matrix body registering only a lower digit different bit string having the different arrangement of the lower digit bit string are registered in each digit in the order of the connection matrix list. In addition, a lower digit connection matrix list index and an upper digit connection matrix list index are formed individually for the lower digit connection matrix list body and an upper digit connection matrix list body. Thus, the occupying capacity of the memory can be reduced sharply and retrieval can be executed easily.
