I took the index of your words, transformed the number to binary, added three zeros, calculated the sha256 digest, took the 1st Element of the hexadecimal to convert it to binary, additional 3 zeros towards the 8 digits in the binary and bought 00000010011 which translates to 19 in decimal. https://www.symbaloo.com/embed/shared/AAAACHlsY-AAA42AhQqHKA==
