Question
One of the one-way functions used in public key cryptography is the discrete logarithm. Computing 

\[ r \equiv g^e \pmod{p} \]

from \( g, e, \) and \( p \) is easy. But given only \( r, g, \) and \( p \), recovering \( e \) is hard.

Suppose \( p = 1607, g = 7 \) and \( r = 464 \). What is the smallest positive integer \( e \) such that 

\[ r \equiv g^e \pmod{p} \] 

?
