    I am going to restart Sheet Analysis because it's unclear and unorganized as before.

    You might check the brand new 'The Sheet Analysis' out here.

    Here is the proof that \(^{\omega 2}\omega\) = \(\varepsilon_{\varepsilon_0}\) or a weaker ordinal \(\varepsilon_1\).


    Ordinal tetration is a type of normal form but we can express ordinals with 0, 1, \(\omega\), addition, multiplication, exponentiation, and tetration.


    The proof require to have 1 new property, OPTD (\(\omega\) power tower depth). Now what's OPTD? A natural number have OPTD 0, \(\omega\) to maximum value that less than \(\omega^{\omega}\) have OPTD 1, and \(\omega^{\alpha}\) have OPTD \(\beta+1\), such that \(\alpha\) have OPTD \(\beta\).

    Also, I also show that \(1+\omega\) = \(\omega\) and \(\omega^{\varepsilon_02}\) have OPTD \(\omega\).


    Imagine 0 is the empty set and \(\alpha+1\) is the union set of all elements of \(\alpha\)…

    Here is reboot version of my array notation, simpler than ever.


    Growth rate: 0
    The simplest and weakest part in AANR (Aarex's Array Notation Rebooted). There is only 1 rule in this extension:

    • r(a) = a+1

    The limit of simple arrays corresponds to FGH level 0 because r(a) evaluates as the same of \(f_0(a)\).


    Growth rate: \(\omega\)
    Let [A]^B = AAA... with Bs, but [A] evaluates, even inside of any [_]s.

    • r(a,0) = a+1
    • r(a,b) = [r(]aa[,[b-1])]a

    If the syntax concentration is too hard for you, here is rules without syntax concentration:

    • r(a,0) = a+1
    • r(a,b)[0] = a
    • r(a,b)[n] = r(r(a,b)[n-1],b-1)[n]
    • r(a,b) = r(a,b)[a]

    To solve r(2,2) (using without syntax concentration):

    • r(2,2) =
    • r(2,2)[2] =
    • r(r(2,2)[1],1) =
    • r(r(r(2,2)[0],1),1) =
    • r(r(2,1),1) =
    • r(r(2,1)[2],1) =
    • r(r(r(2,1)…

    \(D[0]\) is least cardinality and \(D[\alpha+1]\) is greater cardinality than \(D[\alpha]\). Also, \(D[\alpha[D_0]]\) is similar to weakly inaccessible cardinals in OCFs, which:

    • \(\psi_{D[\alpha[D_0]]}(0)[1]\) = \(D[\alpha[1]]\)
    • \(\psi_{D[\alpha[D_0]]}(0)[n]\) = \(D[\alpha[\psi_{D[\alpha[D_0]]}(0)[n-1]]]\)
    • \(\psi_{D[\alpha[D_0]]}(\beta+1)[1]\) = \(D[\alpha[\psi_{D[\alpha[D_0]]}(\beta)+1]]\)
    • \(\psi_{D[\alpha[D_0]]}(\beta+1)[n]\) = \(D[\alpha[\psi_{D[\alpha[D_0]]}(\beta)+\psi_{D[\alpha[D_0]]}(\beta+1)[n-1]]]\)

    Then a new definition happen to prove it WAY stronger:

    • \(D[\alpha[\beta[D[\alpha[D_{\gamma+1}]]]]]\) can be reduced to \(D[\alpha[\beta[D_{\gamma}]]]\), where \(\beta\) must be less than \(D_{\gamma+1}\) and \(\gamma\) > 0.
