In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and ... see more

In this paper we have proved that a Frobenius group of order 301cannot operate on a symmetric block design with parameters (430,78,14).

In this paper it is proved that:A) Up to isomorphism and duality there are exactly two possible orbital structures for a putative symmetric block design with parameters (153, 57, 21) constructed using the Frobenius group F_{17·16}B) Up to isomorphism and ... see more

Context. The object of study of this work is the arrival processes of block symmetric ciphers to the state of a random permutation.Objective. Clarification by means of computational experiments values of dynamic parameters arrival of some modern ciphers t... see more

The paper briefly discusses the balanced incomplete–block design (BIBD’s) and further compares two methods of analyzing them-the classical and vector space analysis of variance (ANOVA) methods. These methods are applied differently to the data arising fro... see more

A finite graph G\Gamma is GG-symmetric if it admits GG as a group of automorphisms acting transitively on V(G)V(\Gamma) and transitively on the set of ordered pairs of adjacent vertices of G\Gamma. If V(G)V(\Gamma) admits a nontrivial GG-invariant partiti... see more

Blockchain technology provides several suitable characteristics such as immutability, decentralization and verifiable ledger. It records the transactions in a decentralized way and can be integrated into several fields like eHealth, e-Government and smart... see more

Statistics has wide uses for making the right decisions in various areas of life, because statistics give a person the knowledge and ability to evaluate data. Through this research, researchers hope to create a new learning model from the results of the d... see more

Practical cracking of Data Encryption Standard (DES) and mathematical cracking of AdvancedEncryption Standard (AES) is seriously questionable despite the fact that AES retains good length of theencryption key, but still it’s all encryption rounds have bee... see more
