List of all classical Bol-Moufang identities is given in [1]. We continue count of number non-isomorphic groupoids of order three with some Bol-Moufang identities [2, 3, 4, 5].There exist 26 non-isomorphic groupoids of order 3 with identity F9, (x.yz)x= x(yz.x) from possible 221 groupoids. There exist 159 non-isomorphic groupoids of order 3 with identity F10, x(y. zx) = x(yz.x) from possible 874 groupoids. Identity F11 xy.xz = (xy,x)z: up to isomorphism there exist 49 groupoids. Identity F12 xy.xz = (x.yx)z: up to isomorphism there exist 45 groupoids. Identity F13 xy.xz = x(yx.z): up to isomorphism there exist 53 groupoids. Identity F13 xy.xz = x(yx.z): up to isomorphism there exist 53 groupoids. Identity F14 xy.xz = x(y.xz): up to isomorphism there exist 61 groupoids. Identity F15 (xy.x)z = (x.yx)z: up to isomorphism there exist 253 groupoids. Identity F16 (xy.x)z = x(yx.z): up to isomorphism there exist 73 groupoids. Identity F17 (xy.x)z = x(yx.z): up to isomorphism there exist 35 groupoids. Identity F18 (x.yx)z = x(yx.z): up to isomorphism there exist 61 groupoids. Identity F19 (x.yx)z = x(y.xz): up to isomorphism there exist 40 groupoids. Identity F20 x(yx.z) = x(y.xz): up to isomorphism there exist 110 groupoids from possible 601. |
