Maybe "we" (i.e. Neil :-) should add HCF to the Index,
(ab)using %N A056582 as definition (?).

I didn't know HCF until I found it some weeks ago in
Davenport's "The Higher Arithmetic", so please don't 
change GCD to HCF. 

For the internationalization of EIS one term could be 
better, but if somebody replaces ln by log, or Ar...h 
by arc...h in one of "my" sequences I wouldn't like it
(and try log hyp or Area ... hyp in a future update ;-)
