In mathematics

[edit]

There are 188 different four-element semigroups,^[1] and 188 ways a chess queen can move from one corner of a $4\times 4$ board to the opposite corner by a path that always moves closer to its goal.^[2] The sides and diagonals of a regular dodecagon form 188 equilateral triangles.^[3]

[edit]

The number 188 figures prominently in the film The Parallel Street (1962) by German experimental film director Ferdinand Khittl [de]. The opening frame of the film is just an image of this number.^[4]
