till you die
I believe it cannot be solved -- levels 1 through 49 were not that difficult -- there is a logic to follow -- level 50 defies the logic and rules so it is not able to be solved.

There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
After you hit level fifty, the levels keep regenerating into random levels.
I believe there's four levels for every world, so if there is eight worlds, there is thirty-two levels!
As many as my little heart desires
The next highest energy electron orbital after 3p is the 4s orbital, after which comes the 3d and then 4p orbitals.
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
The basic reason is historical - although there were many different types of early logic gates the first series that was really used in large volume was the 54xx/74xx series from Texas Instruments - and they operated on a 5V supply and used nominal 0-5V logic levels.
The use of transmission gates eliminates the undesirable threshold voltage effects which give rise to loss of logic levels in pass transistor logic.
Because 4s is a lower energy level and 3d is higher. In fact, s levels should, strictly, be written first before d levels when writing electron configurations.
Yes, Pictometry offers multiple levels of high quality 3D models built from its imagery and a software package for users to create their own, less detailed 3D models.
