Show that there exists a matrix [TEX]A \in M(n,n;R)[/TEX], such that [TEX]m_{ij} \in \{-1,0,1\}[/TEX] and [TEX]det A=1995[/TEX] (I think it can be any other number as well, but the book was printed in 1995 )

My problem is that I don't know what I should do to

__prove__that there

__exist__a certain matrix. I guess I should show such a matrix, but I don't know how to do that anyway.
