Nice find

Some questions, if you don't mind:

1) Who are you replying to, Albert or me ?

2) Nothing else ? No comments on the solutions posted ?

3) In your OP you said you knew only one family of solutions (I've found several). Will you care to elaborate or are you still waiting for additional posts ?

Regards.
