Polyominoes
are plane shapes made by joining squares together - the squares must be
'properly' joined edge to edge, not overlapping like brickwork and not
corner to corner.
One square on its own is called a monomino where as two squares joined
edge to edge is the common domino, triominoes - sometimes referred to as
trominoes - (3 squares), tetrominoes
(4 squares), pentominoes (5 squares), hexominoes (6 squares) etc.
