Three (3)

Widely recognized as the most dangerous of the non-imaginary numbers, the number 3 is highly restricted in usage except on the most primitive worlds, where they have yet to discover complex mathematics beyond first level combat trignonometry.

The tertiary branch of mathematics corps (TBMC) monitor the usage of the number 3 in all media, including this entry, which has been marked "safe" as of galactic date 00224APPLE.

Applications to the TBMC for usage of the number 3, must provide evidence of careful tri-proofing of all materials used in the project, as well as any printouts or hard copies of calculations.
