Dear Firedrakers,

I apologize to insist on the topic of serendipity finite elements. Perhaps my previous message was unclear.
I would like to define some simple serendipity quadratic 8-nodes quadrangles and 20-nodes hexaedrain Firedrake but I do not know how to do it.

Thanks for your help,
Nicolas

Dear Firedrakers,

I would like to use continuous finite elements from the serendipity family. At the moment, I would like to use some simple quadratic 8-nodes quadrangles and 20-nodes hexaedra (the S2 element from the “Periodic table of the finite elements”).
I do not find any tests in Firedrake src (grep -ri functionspace * | grep \"S).
How can I do to use these finite elements?

Thanks,
Nicolas
