I found an example of a discrete funcoid which is not a complemented element of the lattice of funcoids. Thus the set of discrete funcoids is not the center of the lattice of funcoids, as I conjectured earlier.
See the Appendix “Some counter-examples” in my article “Funcoids and Reloids”.
The example is simple diagonal relation.
