A Buddhist book called the Diamond Sutra,printed around 868C.E. yes the oldest known printed book it was printed using page size panels of wood blocks these blocks were carved by hand with Chinese characters shown in Reverse which word or phrase describes the relationship between the ideas and the sentences

The word or phrase that describes the relationship between the ideas and the sentences in the Diamond Sutra, or any other printed book, is "sequence and arrangement." In a printed book, sentences are organized and presented in a specific order to convey a coherent thought or narrative. This sequence and arrangement allow readers to follow the flow of ideas and understand the intended meaning.

Now, returning specifically to the Diamond Sutra, which was printed using carved wooden blocks, the sequence and arrangement of ideas and sentences were determined during the carving process. Each woodblock panel contained a page with a specific section of text, and these blocks were arranged in a sequence to form the entire text of the book. The characters on the wooden blocks were carved by hand in reverse, so when inked and pressed onto paper, they appeared correctly. This process ensured that the sentences and ideas in the Diamond Sutra were presented in a well-organized manner, allowing the reader to comprehend the teachings effectively.

Therefore, the relationship between the ideas and sentences in the Diamond Sutra, as with any printed book, is reliant on the deliberate sequence and arrangement of the text.
