cl-permutation VS bitcoin

Here is Lisp code [1] that maps all sorts of combinatorial objects—permutations, bit sets, base-B integers, multi-set permutations, etc.—perfectly into the smallest set of integers [0, n-1] and back. (In a sense, it's a perfect hash.) This is used to efficiently solve combinatorial puzzles.

Note that in the unlikely event anyone wants to run the code in the post, the algorithm presented is still in an open PR, APIs change until merged, etc.

CL-PERMUTATION has random-perm to produce a random permutation of even, odd, or any parity.

There is a pattern here (that also goes with the author's prior article on inverting gauss' sum formula): Generally if if you can make a formula that counts the combination of things you can convert that into a code to encode and decode those combinations into indexes.

So for example the opus audio codec needs to encode/decode vectors of dimension n whos absolute values sum to k. https://github.com/xiph/opus/blob/master/celt/cwrs.c#L74

Or this rolling cuckoo filter that optimally encode/decode four sorted numbers in a range 0..2N with the constraint that the they span a range of N. https://github.com/sipa/bitcoin/blob/202006_cuckoo_filter/sr...

If you're lucky there will be closed form expressions for the encoding and decoding equations. (There for both of the above, at least for some parameters, but in both those examples the implementations use small tables because for the ranges involved the tables end up being faster than sqrts).

So far we have over 2.8k current traders benefiting from this platform check out website for reference www.bitcoin.org

Watch this and get to watch the whole interview. Now tell me how the owner of www.bitcoin.org (Roger Ver), falsively indicating on the obvious bitcoin website that Bitcoin is Bitcoin Cash and that Bitcoin is now the follow up "Bitcoin Core", not a shill for a coin he GREATLY invested in.

Download Bitcoin core from www.bitcoin.org

Give it a try, or take a look at the screenshots and design paper: Download Bitcoin v0.1 at http://www.bitcoin.org

Yes you can create a wallet within minutes with no ID needed. Just go to www.bitcoin.org and download a wallet based on your needs. However, in terms of actually obtaining/buying the Bitcoin, you may run into some issues with ID. No exchange/platform online will allow you to buy with no ID that I know of. You could always buy from a Bitcoin ATM but even then I think you need to enter your phone number. I could be mistaken in all of this as I've never seriously looked into this and I am going off of what I've read/learned before and things could've changed.

You can download the Bitcoin core software on any PC basically. https//www.bitcoin.org

That is a good start. There is a list if wallets on www.bitcoin.org.
