Keywords:
group; diassociative IP loop; Moufang loop; finite embeddability property; local embeddability
Summary:
We shall show that there exist sofic groups which are not locally embeddable into finite Moufang loops. These groups serve as counterexamples to a problem and two conjectures formulated in the paper by M. Vodička, P. Zlatoš (2019).
