History of the puzzle[edit]
Fitting 12 pentominoes and a 2x2 square into an 8x8 square was the first recorded pentomino puzzle, published by Henry Ernest Dudeney (USA) in 1907. The name pentomino was given by Solomon Golomb in 1953.[2]
This puzzle is the special version of a more general classification, dissection puzzles.
