Yes, I know. In 2016 Scorcher007 wrote interesting blogs about googology in Russian in 7 parts (here is link to part 1) with some errors. He wrote that in then he knew maths worse.

Also, Scorcher007 said that he writes a book about mathematics in Russian. Now I checked his site and apparently he already wrote it: here is link to part 1 (I have not read it yet).

Also, here is link to SLCON notation (I already have seen it) and another table of ordinals (I have not seen it before). And there were another interesting page about maths, I saved it in my computer, but now I failed to find it in that site.
