Some of the cells in the grid are blackened. Fill the remaining cells with the whole set of 12 pentominoes.
Pentominoes may be rotated and/or reflected.
If two pentominoes touch only corner by corner there is a white dot at this corner.
If four pentominoes touch only corner by corner there is a black dot at this corner.
If two neighbour pentominoes touches side by side at a common edge, then the two cells next to this edge are painted with grey.
"Neighbour pentominoes" are defined as following: If you sort the letters of the pentominoes alphabetically the
neighbours stand side by side, as in the following chain:
- F - I - L - N - P - T - U - V - W - X - Y - Z - F - I - ...
So in example neighbours of I pentomino are F and L pentominoes. Or neighbours of Z pentomino are Y and F pentominoes.
All gray painted cells, white and black dots in the grid are given.
Solution code: Row 5, followed by column 7. For each field use the letter of the pentomino. Use letter "E" for the blackened cells.

Finally a Pento puzzle (actually two - V and VI) I could solve and it really made fun! ;-)
