In this paper we show the usability of the Gray code with constant weight words for computing linear combinations of codewords. This can lead to a big improvement of the computation time for finding the minimum distance of a code. We have also consid

Using the method for constructing binary self-dual codes with an automorphism of order square of a prime number we have classified all binary self-dual codes with length 76 having minimum distance $d=14$ and automorphism of order 9. Up to equivalence

For lengths $64$ and $66$, we construct extremal singly even self-dual codes with weight enumerators for which no extremal singly even self-dual codes were previously known to exist. We also construct new $40$ inequivalent extremal doubly even self-d

Data on functional and morphological parameters of seeds of three species of the genus Passiflora L., which were collected in the period from 2014 to 2020 in the greenhouse of the Botanical Garden of Samara University are presented. The collected see

The structure of binary self-dual codes invariant under the action of a cyclic group of order $pq$ for odd primes $p\neq q$ is considered. As an application we prove the nonexistence of an extremal self-dual $[96, 48, 20]$ code with an automorphism o

Trees and shrubs of Rosaceae family possess a significant resource potential for the Samara region ecosystems. The quantitative study of elemental composition was carried out by X-ray fluorescence analysis (XRF) for leaves of 8 introduced and 3 nativ

The purpose of this paper is to complete the classification of binary self-dual [48,24,10] codes with an automorphism of odd prime order. We prove that if there is a self-dual [48, 24, 10] code with an automorphism of type p-(c,f) with p being an odd

All binary self-dual [44,22,8] codes with an automorphism of order 3 or 7 are classified. In this way we complete the classification of extremal self-dual codes of length 44 having an automorphism of odd prime order.

The possibility of seed genetic banks creating is associated with the ability of many plants seeds (the so-called orthodox ones) to maintain germination ability for a long time, being in a dormant state. This opens up wide prospects for the formation
