Abstract: Since ancient times, symmetry has been associated with beauty, harmony, balance, proportion, perfection. The Pythagoreans saw numbers in everything and in numerical relations – the key to unraveling the mysteries of nature. To continue the millennial history of symmetry and the number, this report provides examples of numerical relations that contain symmetries.
Keywords: symmetric numbers, palindromic numbers, perfect numbers, number π.
