Place some of the given pentominos into the grid (not necessarily all of them), using each of them at most once, so that they do not touch each other, not even at a single point. Pentominos may be rotated and/or reflected. Lines denote the direction of the closest pentominos out of the four (horizontal and vertical) directions. In case there are at least two such directions, all of them are indicated with lines. A square with line(s) cannot be covered by any pentomino.
Example:
Puzzle:
Pentominos:
Solution code: Row 6, followed by Column 6. For every cell the letter of the pentomino and '-' for an empty cell.
