Abstract:We show that a positive proportion of the primes have the property that if any one of its digits in base $ 10$, including its infinitely many leading 0 digits, is replaced by a different digit, then the resulting number is composite.

摘要:我们证明,正数的质数具有以下性质:如果将基数中的任意一位数字$ 10 $(包括其无数个前导0位数字)替换为不同的数字,则结果数将为合成数。
