E = (nx 2 + ny 2 + nz 2 ) h2 /(8ma2 ).

Rearranging gives E (8ma2 )/ h2 = (nx 2 + ny 2 + nz 2 )

nx, ny, nz,           1,1, 1       2,1, 1        1,2, 1       1,1, 2       1,2, 2       2,1, 2      2,2, 1       1,1, 3    1,3, 1    3,1, 1

E(8ma2 )/ h2         3               6                 6               6              9               9             9              11          11        11

nx, ny, nz,           2,2, 2      2,1, 3      1,2, 3      3,2, 1     2,3, 1    1,3, 2      3,1, 2      2,2, 3      2,3, 2     3,2, 2 E(8ma2 )/ h2          12            14           14         14           14          14           14             17            17          17     

nx, ny, nz,           1,1, 4         4,1, 1           1,4, 1        1,3, 3         3,1, 3              3,3, 1

E(8ma2 )/ h2           18           18                 18              19                19                   19

TOTAL: 17 states and 6 energy levels lie within this range
