The multiplicative loops of Jha-Johnson semifields

The multiplicative loops of Jha-Johnson semifields

The multiplicative loops of Jha-Johnson semifields are non-automorphic finite loops whose left and right nuclei are the multiplicative groups of a field extension of their centers.They yield examples of finite loops with non-trivial automorphism group and non-trivial inner mappings.Upper bounds are given for the number of non-isotopic multiplicative loops of …
