Abstract
Let denote the prime-counting function and let In this paper we prove that if is an integer and , then does not divide . We also show that if and divides , then . In addition, we prove that if and is an integer, then is a multiple of located in the interval . This allows us to show that if is any fixed integer , then in the interval there is always an integer such that divides . Let denote the sequence of integers generated by the function (where and ) and let denote the th term of sequence . Here we ask the question whether there are infinitely many positive integers such that .
