A digital arrangement (Posted on 2005-06-30) Difficulty: 3 of 5
Without using any arithmetical symbols (+, -, *, /, or similar; other math symbols; decimal comma or periods; letters; even parentheses) or, in short, anything but the digits, build a number with the digits 1, 3, 5, 7 and 9, that is equal to a number built with the digits 2, 4, 6 and 8 (each digit used once and only once).

Note: This is not a trick. It was extracted from a book edited by Angela Dunn, a mathematician who gathered problems that appeared in many scientific periodical revues!

Maybe my comment about their work was misunderstood (the "perception" and "the computer program"), or, once again, the problem of the idiom.

And certainly, when I asked "are the solutions exausted ?", it implied that they had achieve the solution(s). 

My mistake !!
