@rocdocmac Your 2nd solution is the only position I thought possible. plasmid almost have it if he made adjustment of "d7" Salutes for your 2 more solutions!

On the 2 x 1 grid all 7- segment digits above can be formed one at a time as seen on clocks , calculators and other digital devices. If we are allowed to flip or rotate and overlap segments, how should these digits be configured inside the 3 x 4 grid ,so we can see all of them at the same time?

Remove 4 pieces from the above position.. then place them back on any free squares of the chessboard so that no square can be formed by any four pieces on corners of a square . Which pieces to choose and where to position them?

money can buy it

I got five of that one, Just two of another Only one for the none And all of the others.
