729960 is done for the subproject (C106) but i'm keeping it since it has no driver. (2^3 isnt a driver, right?)

Nope, it's not a driver. You should be on a vaguely downward slope now (unless the guide changes). Good luck.

2^n isn't a driver (with no other terms) unless n = 1 in which case it is the down driver. In fact the complete list of drivers with n < 16 is:
2
2*3
2^2*7
2^3*3
2^3*3*5
2^4*31
2^5*3*7
2^6*127
2^9*3*11*31
2^12*8191
