Now I have found a self-made puzzle of one of my seeds. I have about 30-50 seedphrase words here, I have written them down in a pattern that I can't remember. Only with the right pattern can I put the words in the right order.
This seems to be strange to me, how can you have such a big range
.? You should know how many words you have.
So you have 50 words scattered on a piece of paper and you want to find the correct 12 ones in the correct order.
This gives you 50!/(50-12)! = 58,150,627,116,341,760,000 total permutations.
You need 1 out of them.
With 30, that gives him 30!/(30-12)! =41,430,393,164,160,000 total permutations. If I followed your example correctly. Big difference depending on the exact number of words in his case, but still quite unlikely that it will be found this way.
