Abstract: | We consider a class of quasigroup identities (with one operation symbol) of the form x1x2.x3x4 = x5x6.x7x8 and with xi Ε {x, y, u, v} (1 ≤ i ≤ 8) with each of x, y, u, v occurring exactly twice in the identity. There are 105 such identities. They generate 26 quasigroup varieties. The lattice of these varieties is given. |
