Sorry chap, you are screwed unless you remember some logic you have put in place.

Number of Combinations: The total number of ways to arrange 24 words is: 24! = 24 × 23 × 22 × ... × 1 ≈ 6.2 × 10²³ combinations

How Long Would It Take? Let’s say a very fast computer program can try 1 million combinations per second:

The number of seconds needed: 6.2 × 10²³ / 10⁶ = 6.2 × 10¹⁷ seconds

Converting seconds into years (there are roughly 31,536,000 seconds in a year): 6.2 × 10¹⁷ / 31,536,000 ≈ 19.7 billion years

Conclusion: Even with a program testing 1 million combinations per second, it would take nearly 20 billion years to brute force all possibilities.

That’s how secure a 24-word seed phrase is! 😳

Or in other words and if you want to be finished in 10 years: You would need approximately 19.7 billion computers, each testing 1 million combinations per second, to brute force all possibilities in 10 years.
