True, it did already get used in Code D. So the conclusion should be that it was a clue for Code D and not for the HALOS code.

However, it's strange that "21 into 1"  was first posted on the bmrf.us wiki page on the 26th of August, 2014. That's LONG after Code D was solved in November of 2012.

Why would he do that and what does it mean?
