Where the error is zero. In calculating the formula

m \cdot \prod\limits_{i = 1}^n {\frac{{p_i - 1}}{{p_i }}} + n - 1

the number of primes in the interval (0, m)

16633,53704651309*0,1138663409173722+31-1=1924

Approved by the number of numbers m_j indefinitely, it remains to prove this assertion, but it is a matter of time. Sergey.
