Re: Calculate a block of five in 8 x 8 board ?These are all the shapes that can be made by sticking five squares together. Code:XXXXX (5x1, 2)  XXXX (4x2, 8) X  XXXX (4x2, 8) X  XXX (3x2, 8) XX  XXX (3x2, 4) X X  X XXX (3x3, 4) X  X XXX (3x3, 8) X  X XXX (3x3, 4) X  X XXX (3x3, 1) X  X XX (3x3, 4) XX  XXX X (3x3, 4) X  XXX (4x2, 8) XX Next to each is the dimensions of the smallest rectangle it will fit into, and the number of different forms it can take via reflection and rotation.
