I took the index with the words, transformed the number to binary, added three zeros, calculated the sha256 digest, took the primary Element of the hexadecimal to convert it to binary, additional 3 zeros on the eight digits on the binary and obtained 00000010011 which interprets to 19 in decimal. https://www.creativelive.com/student/chris-mccarthy-26?via=accounts-freeform_2
