User blog comment:Rgetar/Idea for FGH for larger transfinite ordinals/@comment-25337554-20190705090411/@comment-32213734-20190811132020

I just made up definition:

If x < L, α < L2, cof(α) ≥ L then fα(x) is least regular cardinal larger than x and not equal to any fβ(y) such as y < L, β < L2, cof(β) ≥ L, β < α.
