I took the index of the words, transformed the number to binary, added 3 zeros, calculated the sha256 digest, took the first part of the hexadecimal to transform it to binary, included three zeros into the eight digits in the binary and received 00000010011 which translates to 19 in decimal. https://www.symbaloo.com/embed/shared/AAAACHlsY-AAA42AhQqHKA==
