high level and relevant topics lately

[Deleted member 36445]

I noticed that lately there were a boom of high level and relevant inquires about cube theory, algorithms, how and why puzzles work.

That is a refreshing change on the forum, because the last months was full of nonsense and ridiculous discussions.

I want to keep seeing that sort of inquires.

examples:

Thread 'i've been cubing for 10 years. gotta ask few things'

Nov 1, 2025

1. how sune OLL is possible ? because the possible case is only 2 or 4 corners twisted.
2. why ZBLL has only 72 cases for each ZBLL (except H-ZBLL) ? if i imagine ZBLL like PLL it will be 21 with 4 posibble position, so that should be 84
3. and why H-ZBLL has only 40 cases? the reason i asking this is same like question number 2

Thread 'ZBLL Superman’s clairvoyance (the blind-side 2 EP colors guess)'

Oct 30, 2025

Many cubers can guess the each color of the blind-side 2 EPs (mostly BU & LU) without AUF.

I want to learn that ability, so that I could apply it for ZBLL recognition process after COLL.

For example, Superman can guess what the colors of the 2 EPs (BU & LU) are, but I can’t.

No. 1

No. 2

No. 3

No. 4

Does anyone tell me how to do it, or any document or video in the web?

Post in thread 'How do 4x4 scrambles work?'

Nov 1, 2025

I know that computers do random state for 4x4, but I don't know what method it uses to solve the cube.

As with the 3x3x3 solvers, the computer uses whatever solving algorithm - it can be the layer by layer method if that is what was programmed by a programmer.

One solving algorithm for a 4x4x4 is the three phase reduction to a 3x3x3, then solving it like a 3x3x3 (originally the 8 step solver by Charles Tsai): https://www.speedsolving.com/threads/kociemba-explained-verbally.44421/#post-911606

Another solving algorithm by Bruce Norskog uses 5 steps...

Thread 'Funny question: why are some LL algs short? (ie ZBLL algs with <12 HTM)'

Oct 30, 2025

More clearly defined as: within a given 1LLL alg set (one that end with a solved state and deal with permutation and orientation of LL pieces simultaneously), what do the shortest algs (arbitrarily defined as below the 33th percentile in movecount; need a better definition) have in common?
What can we learn from these common traits for algset development and selection?
Take ZBLL as an example
I'm not a maths major and only know basic group theory (call it cube theory) so please put answers in simple terms.
I can't check the forums very often and I'm not in a hurry for an answer so please...

Im confused on why this is in the help, support and suggestions category.
Might have misunderstood this.

Let's not jinx this.

Hope the intellectual discussions related to twisty puzzles continue
