    en.wikipedia.org/wiki/76_mm_mountain_gun_M48

    The M-48 (B-1A2) has light alloy wheels with solid rubber tyres and modified suspension, its maximum towing speed is 30 km/h. The final production model of the 76 mm mountain gun M48 was called the B-2 about which little is known. The Tun de munte calibru 76 mm model 1982 was a Romanian built version which equipped mountain, paratroop and naval ...

    en.wikipedia.org/wiki/2,147,483,647

    The number 2,147,483,647 is the eighth Mersenne prime, equal to 2 31 − 1. It is one of only four known double Mersenne primes. [ 1 ] The primality of this number was proven by Leonhard Euler, who reported the proof in a letter to Daniel Bernoulli written in 1772. [ 2 ] Euler used trial division, improving on Pietro Cataldi 's method, so that ...

  6. Frattini subgroup - Wikipedia

    en.wikipedia.org/wiki/Frattini_subgroup

    In mathematics, particularly in group theory, the Frattini subgroup of a group G is the intersection of all maximal subgroups of G. For the case that G has no maximal subgroups, for example the trivial group {e} or a Prüfer group, it is defined by . It is analogous to the Jacobson radical in the theory of rings, and intuitively can be thought ...

  7. Zorn's lemma - Wikipedia

    en.wikipedia.org/wiki/Zorn's_lemma

    Zorn's lemma says that a maximal tree must exist, which is a spanning tree since the graph is connected. [1] Zorn's lemma is not needed for finite graphs, such as the one pictured here. Zorn's lemma, also known as the Kuratowski–Zorn lemma, is a proposition of set theory.

  8. Maximal and minimal elements - Wikipedia

    en.wikipedia.org/wiki/Maximal_and_minimal_elements

    The red subset = {1,2,3,4} has two maximal elements, viz. 3 and 4, and one minimal element, viz. 1, which is also its least element. In mathematics , especially in order theory , a maximal element of a subset S {\displaystyle S} of some preordered set is an element of S {\displaystyle S} that is not smaller than any other element in S ...

    en.wikipedia.org/wiki/Amdahl's_law

    For example, assume that we are given a serial task which is split into four consecutive parts, whose percentages of execution time are p1 = 0.11, p2 = 0.18, p3 = 0.23, and p4 = 0.48 respectively. Then we are told that the 1st part is not sped up, so s 1 = 1 , while the 2nd part is sped up 5 times, so s 2 = 5 , the 3rd part is sped up 20 times ...
