​Done!

#%%
# hierarchical row levels
arrays = [['layer0'] + ['layer1'] * 12 + ['layer2'] * 42,
          range(1 + 12 + 42)]

tuples = list(zip(*arrays))
rowindex = pd.MultiIndex.from_tuples(tuples, names=['Shell', 'Ball'])
#%%​


​Those weird %% thingys are I-Python / Spyder's way of letting run down a
script in discrete chunks.

To give a sense of the data:

Vtype       ivm             xyz
Coords        a  b  c  d      x      y      z
Shell  Ball
layer0 0      0  0  0  0  0.000  0.000  0.000
layer1 1      0  1  1  2  0.000 -0.707 -0.707
       2      0  1  2  1 -0.707  0.000 -0.707
       3      0  2  1  1 -0.707 -0.707  0.000
       4      1  0  1  2  0.707  0.000 -0.707​

Great for anyone into linear algebra at all.
