A complete description of all possible multiplicative groups of finite skew left braces whose additive group has trivial centre is shown. As a consequence, some earlier results of Tsang can be improved and an answer to an open question set by Tsang a

The aim of this paper is to introduce and study the class of all left braces in which every subbrace is an ideal. We call them Dedekind left braces. It is proved that every finite Dedekind left brace is centrally nilpotent. Structural results about D

An inventory of the ichthyofauna of the Aquidauana and Miranda basins is presented. A total of 9,559 individualsof six orders, 21 families and 68 species were sampled in streams (n = 6), rivers (n = 2), and reservoirs (n = 5) during thedry and wet se

We show that the number of isomorphism classes of left braces of order~$64$ with additive group isomorphic to $C_2\times C_2\times C_4\times C_4$ is $10\,326\,821$. This completes the classification of left braces of order~$64$, that turn out to fall
