Some eagle-eyed readers of Artemis have spotted a few errors; printing, plot or maths, and have been quick to point them out.
1. The Safe
When Jazz tries to open Jin Chu's hotel room safe she sees that his code includes the numbers 0, 1 and 7. As the code must be 4 digits she concludes there must be 54 different combinations.
Some fans have argued that it should actually be 36 different combinations.
3. Fiber Optics
1st hardback edition of Artemis pg 189 - Jazz says that fiber optic lines can only be 15km (9.3 miles) long without the use of repeaters but we currently have fiber optic cables in use that are 80-100km (49-62 miles) long without repeaters. A single strand of fiber might only be manufactured at 15km, but they can be fusion spliced together to make longer runs.
