- Illegal number (Wikipedia)
An illegal number is a number that represents information which is illegal to possess, utter, propagate, or otherwise transmit in some legal jurisdiction. Any piece of digital information is representable as a number; consequently, if communicating a specific set of information is illegal in some way, then the number may be illegal as well.

ALIOTH (Epsilon Ursae Majoris). The graceful curve of handle of the Big Dipper (the Plough in Great Britain), among the most famed of celestial sights, represents the tail of Ursa Major, the Greater Bear. Third star in from the end, “Alioth” relates not to a bear, but to a “black horse,” the name corrupted from the original and misassigned to the naked-eye companion of Mizar, which took on the vaguely similar name “Alcor.”
