User blog comment:Wythagoras/Strength of Hierarchical Nested Subscript Array Notation/@comment-7484840-20130730134356

as soon as HAN starts using subscript, it also needs to have a universal bracket put round the outside: just an extra set of []'s. This does have an implication on the comparisons because the universal bracket has a similar affect to the theta function, and the stuff inside the Omegas. This means that:

$$\vartheta(\Omega_{\theta(\Omega_{\varepsilon_0})}) = _{[[_{[1,1,1,1,2]}1}1]]$$, and that $$\vartheta(\Omega_{\Omega_{\varepsilon_0}}) = _{[_{[1,1,1,1,2]}1]}1$$
