They are correct.

They are almost all correct. Only one is wrong:252th.
I'm not sure what you meant by "(I will feed them to it to test it's learning capability)" in your original thread.
PS it's learning should be its learning.
The program, I presume- give it a limited list and see if it can generate any number correctly, including vast, implausible numbers.
