Nice, mathmaniac!

Here's mine : X can be cut down from the middle and separate the upper V and the lower V. Hence, X = 2 * V. Now, we see that it is an universal truth and consistent with any other mathematical axioms in

+ | 1 | 9 | 10 |

1 | 10 | 1 | 9 |

9 | 1 | 9 | 10 |

10 | 9 | 10 | 1 |

(Or alternatively, $G=\mathbb Z/2\mathbb Z$.)
