It has been conjectured by Bensen and Jacoby that no nontrivial bimagic squares of order less than 8 exist. This was shown for magic squares containing the elements 1 to "n" by Boyer and Trump. However, J. R.
FORK-256 FORK-256 FORK-256 is a hash algorithm designed in response to security issues discovered in the earlier SHA-1 and MD5 algorithms. After substantial cryptanalysis, the algorithm is considered broken. In 2005, Xiaoyun Wang announced an order-formula_1 collision attack on the government's hash standard SHA-1. The National Institute of Standards and Technology (NIST), the body responsible for setting cryptographic standards in the United States, concluded this was a practical attack (as previous estimates were order-formula_2) and began encouraging additional research into hash functions and their weaknesses. As part of this effort, NIST hosted two workshops where potential new algorithms, including FORK-256, were
