cyclic number

C2Number Theory

(technical, academic)An integer that, when multiplied by consecutive integers, results in products that are rearrangements of its digits.

Example

• The number 142857 is a cyclic number because multiplying it by any integer from 1 to 6 results in a rearrangement of its digits.
• When 142857 is multiplied by 3, the result is 428571, which is a cyclic permutation of the original number.
