This is a very important topic that I want to comment on, since lately I see a lot of confusion on it on Twitter and in other platforms about Whats the difference between a 12 word seed phrase and a 24 word seed phrase? Many people simply have a basic preference or default wallet. For some, like me, the issue goes further, and is about security, i will try to summarise it as quite as posible. I will split this topic in three parts: 12 words seed phrase , 24 words seed phrase and finally the scrambled Seed Words.
Note: SP will stand to seed phrase.
12 Words SP
And if you are wondering wich words are in the BIP39 list here its is a llink to check it by yourself.
https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt
The number of posible combinations exceeds 2.6 undecillion potential pairings. This implies that in order to calculate all of the potential 12-word SP that exist, someone would have to predict all 2.6 undecillion permutations, quite a heavy proces to be honest.
24 Words SP
As you see 14 quattuorvigintillion possible word combinations, its the first time you heard it, i know....
Astronimcal number, although guessing a 24-word seed phrase is not impossible in theory, we can described as "practically impossible." In other words, given the constraints of a human lifespan and the full extent of computer power now accessible to humanity, it is not conceivable to estimate a seed phrase (Who knows in the future...).
Scrambled SP
Two cases the 12 and the 24 SP case.
So here we will gonna talk about having the correct list of words but scrambled, in wich case we can restore our wallet its is posible? two cases the 12 and the 24 SP case.
Starting with the 12 scrambled words:

The list above is a 12 word SP scrambled, that contained 100,000 sats in this adddres: bc1ql7ka7ut3vcveydx8sy9ylhurpnc6cpy02yjrge
A web page throw it as a challenge in November 13, 2022 and in December 8, 2022 the sats were gone.
So, in order to guess the order of 12 known seed words, you have to guess all 479,001,600 possible combinations. Thats less than half a billion different combinations. It probably wouldnt take someone very long to guess with the right computer script and a decent amount of computing power.
The 24 scrambled words:

Thats more than 620 sextillion possible combinations, which is more than one quadrillion (1,295,295,050,649,600) times the number of possible combinations with just 12 words. Thats the power of Vires in numeris, or strength in numbers, which is one of the many mantras that bitcoiners put on t-shirts, artwork, and cliché engagement tweets. The raw level of security that you have with a 24 word seed phrase is essentially 1,295,295,050,649,600 times greater than with just 12 words.
Conclusion
Using this examples, i want to conclude this topic saying that both 12 and 24 SP words are secure, but 24 is way more, in one hand we have the dilema of scrambling the words and having the 24 SP its would be imposible to recover, although the 12 SP its definetly more ''easy'' or '' lot less difficult'' than the 24 one. My suggestion is to pick the 24 SP and not scrambling the words , i hope you learned something.
