알고리즘은 먼저 그것을 기본 26 숫자로 변환 A-Z하여 0-25처리 한 다음를 더 56*252**4합니다.

그런 다음 숫자는 5 자리 기본 252 숫자로 변환되고 해당 순열 5 0초와 5 1초로 대체됩니다 .

그 후에는 처음 2 비트를 삭제하십시오 01. 그런 다음 문자열을 정확히 24 0초와 24 1초로 구성된 48 비트 문자열로 인코딩했습니다 .

                  at the specified indices and 0's elsewhere.
                  Since the maximum of the combination is 42, this list will have
                  exactly 42 items, 21 of which will be 1's.
