User blog:MilkyWay90/My ordinal function

a0(n) = lvln(n, n) or n ↑↑...n↑n

F(x, a(n)) = F(x - 1, ax(n))

F(1, a(n)) = a(n)

ab + 1(n) = F(n, ab(n))

ab(n) = F(n, ab[n](n)) if b is limit ordinal where b[n] denotes the nth element of the fundamental sequence of b

How is this compared to the FGH, HGH, and SGH? Feel free to leave the answer or/and any comment in a comment!
