A choice combination is a series of choices made from among several possibilities. When several options have several choices (multiple choices: numbers, letters, colors, or other choices), then it is possible to list all the combinations of choices offered.

Enter the choices on each line in the generator and click on generate button

__Example:__ All clothes combinations among 3 colors and 5 sizes:

1st multiple choice, the color `red, green, blue`

2nd multiple choice, the size `XS S M L XL`:

red | XS |

red | S |

red | M |

red | L |

red | XL |

green | XS |

green | S |

green | M |

green | L |

green | XL |

blue | XS |

blue | S |

blue | M |

blue | L |

blue | XL |

The total number is equal to the multiplication of the number of each possible choices.

__Example:__ A car that can have 5 choices of colors, 2 choices of engine and 2 choices of gearbox, will have $ 5 \times 2 \times 2 = 20 $ distinct possibilities

__Example:__ A 3-digit padlock with 10 choices for the first digit, 10 choices for the second digit and 10 choices for the last digit will have $ 10 \times 10 \times 10 = 1000 $ possible combinations.

Filtering the results is a completely different operation which is not proposed here.

dCode offers a page dedicated to filtering number combinations.

For letter combinations to form words, dCode offers dedicated word search tools (like regular expression word search).

Combinatorial explosion is a phenomenon where the total number of possible combinations increases exponentially as the number of elements or options to be combined increases, often making the generation of these combinations impractical for large numbers of elements. To avoid this, limit the number of elements to choose from to reduce the complexity of the problem.
