The pseudo Smarandache function, Z(n), introduced by Kashihara [1], is as follows:
For any positive integer n, the Smarandache function S(n) can be defined as follows: S(n) is the smallest number, such that S(n)!
This paper as a note of Gou Su's work, we consider the hybrid mean value properties of the Smarandache kn-digital sequence and Smarandache function S(n), which is defined as the smallest positive integer m such that n|m!.

Now we let S(n) be the Smarandache function. That is, S(n) denotes the smallest positive integer m such that n divide m!, or S(n) = min{m : n | m!}.
For any positive integer n, the famous Smarandache function S(n) is defined as the smallest positive integer m such that n | m!.
