List of googolisms/5~6 linear

After this discussion, the size class system was redesigned; the numbers used to be on this class are now split over two classes. Go to:
* List of googolisms/Quadratic omega level for numbers below \(f_{\omega^3}(10^{10^6})\); or
* List of googolisms/Polynomial omega level for numbers above \(f_{\omega^3}(10^{10^6})\).
