You just map the value (1, 1) to the value 1 of , and it works out. E.g. for , the group generated by of (1, 1) is:
0 = (0, 0)
1 = (1, 1)
2 = (0, 2)
3 = (1, 0)
4 = (0, 1)
5 = (1, 2)
6 = (0, 0) = 0
Free gifted education by Ciro Santilli 35 Updated +Created
This term was invented by Ciro Santilli, and similar ideas certainly already exists with different names by other people. As the name suggests, it basically involves combining free education and gifted education, but with other more specific aspects crammed in that would make a precise name too long to read, as descried below.
Government must create selective, K-12 and university-level teaching institutions that are completely free.
As mentioned at pick few good bets and invest enough on bets, these do not need to be given to all students: what we have to do is to ensure that the top N-percent of the best students will get in, and that none of them will pay. Where N is as large as the budget society decides to put into this project, the larger the better. Therefore, perhaps "gifted education" is not the ideal name for this idea, as it generally implies very small N (1%?), while this project hopes for larger N, maybe 10%. But a minimal level of quality must be attained, it is pointless to dissolve the resources too much, if we only have enough for 1%, then so be it, start with 1%.
These institutions must start from the very first school year, and go all the way up through K-12 to the end of university. It is useless to start at university-level only otherwise only the rich students will have a chance of getting in, like Ciro Santilli saw in Brazil at the Polytechnic School of the University of São Paulo in the late 2000's: one day all students were gathered in the amphitheater, and they asked the students who had only gone through free government K-12 schools to raise their hands. Those were notably worse than the corresponding private schools, and the situation is inverted in university, where the best schools are the government ones. Out of about 500 people, at most 10 raised their hands!
These institutions should not have affirmative action entry quotas, including most importantly at the university level. Both rich and poor should be able to apply. Passing the selection criteria is all that matters. We just must ensure that the schools are widely advertised amongst disadvantaged communities, so that they will at least get their children to try to apply from an early age. This way, even if the rich always have an advantage due to better overall conditions, the poor are so much more numerous that the majority of students accepted will still be poor.
The school should follow the basic principles of how to teach, notably:
These schools must pay mentors as much as the average good non-free schools so you actually get comparably good teachers. Mentor selection would also be highly competitive, just as that of the students.
Once admitted, students will have guaranteed access to the school resources for a few years. This way, they won't need to worry about passing useless exams every three months.
All that matters is that they are progressing in their development plan. Rather than exams, students will do regular progress report sessions with their advisors, and will get periodic reviews from other advisors with similar interests.
Such projects could be funded by much needed wealth tax or other measures to tax the rich, which the people should claim through Referendum, that would be come more common with the adoption of electronic voting. Because the politicians are simply not being able to do it.

Reactions to cirosantilli.com by Ciro Santilli 35 Updated +Created
Deep psychological analyses:
All IP ranges have some holes in them for which we don't have a domain name.
It is because there was nothing there, or just because we don't have a good enough reverse IP database?
It is possible that DomainTools could help with a more complete database, but its access is extremely expensive and out of reach at the moment.
Censys is another option that would be good to try.
Putting 140 USD into WhoisXMLAPI to get all whois histories of interest for possible reverse searches would also be of interest.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
