(1) Digits of principal factor.
(2) Digits of the critical factor (by definition the 2nd largest prime of the complete factorization of the principal factor). If the critical factor is not known, we present the next smaller known prime factor with an asterisk. If two Chebyshev integers have the same critical factor digits, the larger one comes first. To find the actual factors go to the relevant Factorization Tables. To find the definition of the principal and critical factor go to Explanation of the Tables.
