By "isn't equal to anything" I mean that it has no number value and it cannot be evaluated in any way.If we say F(n) = F(F(n-1)) and F(1)=2 like in Sbiis Saibian's blog post "Introduction to googology" is not a function by the standarts of MBOT.F(1) is,but F(n) isn't,because it cannot be evaluated.
