Download of a small applet ("mag5x.exe", 51 kb), written in VB 5, expected to run under every MS Windows version.
The applet generates all 5x5 magic squares, where entries may be prescribed by the user.
fixed entries
the user may prescribe fixed entries, if no fixes are made,
the program starts with the first possible 5x5 magic square
(in lexicographical order).

the user made entries are tested; a passed test means no guaranty,
that there exists a 5x5 magic square with these entries.

the search for 5x5 magic squares begins.
causes a break, the user is asked whether to continue or not.

fixed entries are displayed in red colour;
the grey numbers show the algorithm in action.

date and time are displayed when the computation starts
and when the computation ends.

solution number and the last found solution are displayed.

stop at next solution
causes a break, when the next solution is found.
