A D number, also known as a 3-Knödel number, is a number n > 3 such that n divides kᶰ⁻² - k for all integers k such that 1 < k < n and k is relatively prime to n. This means n has a unique relationship with powers and modular arithmetic, making it a fascinating topic in number theory. For example, consider the number 51. The number 51 is D number because it satisfies the condition that 51 divides kᶰ⁻² - k for every integer k that is relatively prime to 51 and lies between 1 and 51.
Understanding the previous and next D Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types.
