WebSep 10, 2016 · A simple technique to form a cyclic group G of prime order q such that the underlying discrete logarithm problem (DLP) is (conjecturally) hard, applicable to large q (in the order of a thousand bits), is to pick q as a random prime of appropriate size such that p = 2 q + 1 is prime, and any integer g with 1 < g < p − 1 such that g q mod p = 1.

WebThe simplest case for you is to consider prime number p of the form p = 2. p 1 + 1. Where p1 is also prime. The structure of the multiplicative group of Z n = { 1, 2,..., p − 1 } splits into 3 subgroups of order 2, p 1, p-1. Only quadratic non residue residue have maximal order. elements of order 2 are 1 and p-1. Web1) a cyclic group is simple iff the number of its elements is prime; 2) Abelian simple groups are cyclic; 3) the smallest non-cyclic, but simple, group has order 60. Greetings,... spvie by luca

WebJun 5, 2024 · We can express any finite abelian group as a finite direct product of cyclic groups. More specifically, letting p be prime, we define a group G to be a p -group if every element in G has as its order a power of p. For example, both Z 2 × Z 2 and Z 4 are 2 -groups, whereas Z 27 is a 3 -group. WebSince G has two distinct subgroups of order 3, it can-not be cyclic (cyclic groups have a unique subgroup of each order dividing the order of the group). Thus, G must be isomorphic to Z 3 ...
