ʠ999₵₵₵₵...₵₵₵₵ʠ999, with ʠ99999 ₵s is somewhere between q99999 and q100001.

As you can see, since q_n is already stronger than repeated ₵s, there's no point in combining the two.

What you really want here, is to repeat the application of q. Why limit ourselves to q126 or q99999 when we can have any number after the q?

how about qgoogol?

Or qq 999999 ?

Or qq q 999999 ?

Not a very big jump, mind you, but at least it gets you from 4 arrows to 5 (from "hexation" to "heptation").
