All the works presented in this pages are build using my mind in the hope it will be useful. My reserch is not finish (I will have to find a 191 prime order, the doubles squares for the other orders...) but I have little free time to do the reserch. The programs I write and algoritms I describe may be used for non commercial porpuse (some of them are with GPL license), because reserch may be for all people.
I think that the 191 order may be found using my latest algoritm or an algoritm that first make diagonals magics and than the row and columns without change the diagonals value.

Good reserch...
