Check Character Systems Using Quasigroups: II
In this part of the article we continue to research check character systems with one check character over quasigroups under check equations which have one permutation. These systems always detect all single er...

Check Character Systems using Quasigroups: I
We consider check character systems with one check character over an arbitrary quasigroup under different check equations which have one permutation. The aim of using such a system is to discover transmission ...
