Finding MV algebras with Sage

I would like to find with Sage in a quick way all finite lattices having a partial operation xy, defined for xy, satisfying the following properties:

(a) xyz: xzxy and (xy)(xz)=yz

(b) xy,z: x(yz)=xyxz

(c) (xy)y=x(xy)

(d) xy: yxy and (xy)y=x

This is equivalent to having the structure of an MV algebra (see Prop. 44 on page 34 of https://pnp.mathematik.uni-stuttgart.de/iaz/iaz1/Rump/32-35.pdf).

Such lattices are always distributive.

I would be grateful for any help.
