How do I access to connectivity of the Tetra10?

Coreform Cubit Meshing

I am trying to access to connectivity of the Tetra10?
The following script gives me only four nodes.

cubit.cmd('create sphere radius 1 ')
cubit.cmd('volume all scheme tetmesh')
cubit.cmd('volume all size auto factor 10')
cubit.cmd('mesh volume all')
cubit.cmd('node visibility on')
cubit.cmd('block 1 add volume all')
cubit.cmd('block 1 name "MAT"')
cubit.cmd('block 1 element type TETRA10')
print(cubit.get_connectivity("tet", 1))
#2

I could obtain 10 nodes with
print(cubit.get_expanded_connectivity(“tet”, 1))

Thank you.
