Hi. I was wondering if anyone can help me out here??? I just generated a new coinomi wallet and it gave me two of the exact same words back to back in my 24 word recovery phrase. The penultimate two words before the last one in my phrase are the exact same. I thought that was weird as I was under the impression that they're meant to be randomly generated and the odds of that happening must be astronomical.
The words are simply encoding 11 bits of data... so out of your groups of 11 bit sequences, if you have two that are identical, you'll get the same "word" shown in your mnemonic.It's not that uncommon... I helped a fellow out a while back who only had 23 words written down out of a 24 word seed mnemonic. Turned out, after my script managed to bruteforce the correct seed mnemonic, that the missing word was identical to the one next to it, which explains why he missed it out when writting it down!
