I think this is roughly accurate!

Let's draw a PYRAMID of the Foundations of Set Theoretic Mathematics.

* MATHS SOLVER *
* LOGIC DATABASE *
* COMPUTING MODELS *
* {a{a b}} {{{}} {}} * s>t>r>i>n>g>s & n^u^m^b^e^r^s
* {{{}}{}{{{{}{}}}}}}} *
* HIERARCHY OF NULL SETS *

Frankly I think {1,{1,2}} <=> <1 2>

is taken a little too far here, note the BASE LEVEL SETS
are practically un-usuable and it has to emulate a dictionary
of strings to start again on that higher foundation level
without needing the null-set architecture from level 3 up!

so which came first...

the STRING OF ALPHABET SYMBOLS or the HIERARCHY OF NOTHING?
