I have studied the Smarandache Happy Cube Numbers and I have got some interesting results and facts . I have discovered some open problems a bout the Happy Cube and Smarandache Happy Cube Numbers
A positive integer is called Fixed Happy Cube Numbers (FHCN) in case, if you are cubing its digits and adding them together one time you got the same number. For example the number 153 is happy cube because; 153= 1^3+5^3+3^3, ...
The main purpose of this paper is to introduce new concepts of Smarandache
numbers, namely Smarandache Sequence of Unhappy Numbers, and give definition,
theorem, and ask open problems.
