Note.
1968, dual role of the basis functions of serendipity finite elements is proved by
O. Zienkiewicz
1982, triple role of the basis functions of serendipity finite elements is proved by
A. N. Khomchenko. He solved the paradox of Zienkiewicz in a constructive form,
and is the founder of the scientific school of the constructive theory of serendipity
approximations
2016, quadruple role of the basis functions of serendipity finite elements is proved
by D. Topchyi
