Aleksandr Benckendorff was charged with hunting them down, and many had been members of the Union of Salvation and the Union of Welfare. Five of them were officially executed including Pavel Pestel who organized the Southern Society and the poet Kondraty Ryelev who hoped that his Northern faction's refusal to support Nicholas I's ascension would spark an uprising that would leave Prince Trubestkoy as dictator. FTP identify this mostly upper-class group of Russian revolutionaries whose 1825 rebellion failed and who are named for the month in which their aborted operations took place.
History

Victims are special types of these that store entries that were removed from the general type of them. Ones with a no-write allocation policy do not need to worry about the decision to write-through or write-back. Misses in them include compulsory misses, which generally must occur on the first request, as well as conflict misses that result from an entry once in them having been evicted. In cases where data can be placed in exactly one place in them they are known as direct mapped, while the set associative type provides a compromise in locations between direct mapping and fully associative. FTP, identify this term which names a type of memory faster than the RAM accessed by the CPU, as well as for data your web browser stores locally on your hard drive.
Science

This statement contributes to the repulsive one over r to the twelfth term in the Lennard-Jones Potential. Its rigorous statement requires that particles with half-integer spin have anti-symmetrical wave functions, and it also explains neutron degeneracy, which prevents smaller neutron stars from collapsing into black holes. The "+1" term seen in the denominator of the Fermi-Dirac distribution arises due to this statement, and bosons do not have to obey it, but fermions such as protons and electrons do. For 10 points, name this law of quantum mechanics, which states that no two identical fermions can occupy the same quantum state at the same time.
