Do we have any clue on the sequence of the words in the seed phase?


Even with a finite list of 12 words, given the computational limits and the astronomical number of permutations, shuffling and processing all combinations of 12 words from a BIP-39 word list is infeasible.

Even with extremely fast processing, the time required is on the order of 10^33 years, which is far beyond any practical time frame.

Consider a mnemonic phrase like this one from the picture:

"subject camera tower mask police liberty eye black pyramid vote moon rifle"

But what is the password?

Or what is the BTC address index from m/44'/0'/0'/0/0 to m/44'/0'/0'/0/100 ?  Grin

This can be easily checked from https://iancoleman.io/bip39/ or even with coding.
The problem is indeed here:

which is 8,916,100,448,256 combinations just for 12 word combination of phrases. Even then, it is not yet clear if the phrase is actually only 12 words or more and if it has any Bip39 optional passphrase.

From what I have noticed in all my time generating millions (and possibly even billions because I wasn't really counting every time) of mnemonic phrases in Python and Java, usually the legacy (compressed) address in question is the first one, no matter if it is BIP44 (Blockchain.com) or BIP84 (TrustWallet). (I confirm it using https://iancoleman.io/bip39/)

Though even if we have so many clues here and a literal Github repo () just for this puzzle, all the clues together create quite a lot of confusion.
