1. Pentomino

   Derived from the Greek word for '5', and "domino", a pentomino (or 5-omino) is a polyomino of order 5, that is, a polygon in the plane made of 5 equal-sized squares connected edge-to-edge. When rotations and reflections are not considered to be distinct shapes, there are 12 different free pentominoes. When reflections are considered distinct, there are 18 one-sided pentominoes. When rotations are also considered distinct, there are 63 fixed pentominoes. Pentomino tiling puzzles and games are popular in recreational mathematics. Usually, video games such as Tetris imitations and Rampart consider mirror reflections to be distinct, and thus use the full set of 18 one-sided pentominoes. Each of the twelve pentominoes satisfies the Conway criterion; hence every pentomino is capable of tiling the plane. Each chiral pentomino can tile the plane without being reflected.

1. Pentomino

   A pentomino is a polyomino composed of five congruent squares, connected along their edges. There are 12 different free pentominoes, named after the letters of the Latin alphabet they resemble. Ordinarily, the pentomino obtained by reflection or rotation of a pentomino does not count as a different pentomino. The F, L, N, P, Y, and Z pentominoes are chiral in two dimensions; adding their reflections brings the number of one-sided pentominoes to 18. The others, lettered I, T, U, V, W, and X, are equivalent to some rotation of their mirror images. This matters in some video games, where mirror image moves are not allowed, such as Tetris-clones and Rampart. Each of the twelve pentominoes can be tiled to fill the plane. In addition, each chiral pentomino can be tiled without using its reflection. John Horton Conway proposed an alternate labeling scheme. He uses O instead of I, Q instead of L, R instead of F, and S instead of N. The resemblance to the letters is a bit more strained, but this scheme has the advantage that it uses 12 consecutive letters of the alphabet. This scheme is used in connection with Conway's Game of Life, so it talks about the R-pentomino instead of the F-pentomino.

1. PENTOMINO

   A pentomino is a shape made of 5 congruent squares that are connected by their edges(sides). There are 12 pentominoes(I, F, X, U, V, W, N, T, X, Y, Z, P). t The rotation or reflection of on of the pentomino is not counted. The pentominoes are named by how they look. For example, U is a cup.
