Access is available to Clearance 2 personnel for research and investigation, subject to approval b by Clearance 3 personnel with a principle scholastic focus in mathematics.
Description: SCP-XXXX is a group designation to ███ copies of a mathematical puzzle book, similar in design and manufacture to sudoku books commonly seen sold in grocery stores. SCP-XXXX is a neon green, 96 page paperback book entitled "Inredible Methmetical Puzles 2 Xcite Ur BRAIN!" [sic]. Further investigation shows that SCP-XXXX was copyrighted in the year ████ by Educat Publishing House, which has also published SCP-████ and SCP-████.1
The content of SCP-XXXX consists of a series of anomalous mathematical puzzles and theorems, many of which seem entirely logical to the reader but are entirely contradictory to the standard axioms of mathematics. Examples include:
List of Puzzles
| Page Number | Puzzle/Theorem Description |
|---|---|
| Page 6 | A discussion of the famous Konigsberg problem, solved by Euler in the eighteenth century. A theoretically impossible one-circuit path of the graph is presented. |
| Page 12 | The three utilities problem is presented. Subjects testing the book have no problem whatsoever finding a perfectly valid solution to the problem. |
| Page 14 | Instructions are presented on how to create various four-dimensional objects - such as a hypercube and a non-intersecting Klein bottle - in three-dimensional space. |
| Page 15 | Instructions are presented on how using the axiom of choice can be used to carve an orange into two oranges, or a small orange into a much larger orange. Subjects testing the book have repeatedly demonstrated the ability to perform the necessary cuts and movements once they have read the instructions. |
| Page 21 | Readers are tasked with writing a proof of Fermat's Last Theorem using only mathematical knowledge Fermat would have had available at the time of his death. Three logically consistent proofs have been generated in testing. |
| Page 25-29 | A quiz for Hilbert's 23 questions - answers listed on the last page indicate that the continuum hypothesis, Riemann hypothesis, and Goldbach's conjecture are all true. A proof that the axioms of arithmetic are consistent - within arithmetic - is also presented.2 |
