We propose a new type of multi-soliton solution to the box and ball system which is a completely discrete soliton system. The solution follows a form of ultradiscretized permanent which is defined by a signature-free determinant. Moreover, we show the solution is equivalent to a known type of solution and give a direct proof of solution.
