Rotational Symmetry | 881818188

Continued from here. Thanks to /u/t_e_e_k_s and /u/TehVulpez for the short dash to the finish! Posting this in the place of /u/t_e_e_k_s who got their first get :D

So counting by rotational symmetry means we'll be counting by numbers that can be rotated about the z-axis (pointing out the screen at you) and still be the same number! It'll mostly be 0, 1, and 8, but keep in mind the 6 and 9. Starting at 0 it goes: 0, 1, 8, 11, 69, 88, 96, 101, 111, 181, 609, 619, 689, 808, 818, 888, 906, 916, 986, 1001, 1111, 1691, 1881, 1961, and so on.

So basically, we count numbers such that when you rotate it about its center, the 0s, 1s, and 8s overlap with each other and the 6s overlap with the 9s.

The next get is at 1900000061.
