	COMMENT	`This sequence and A087802 first differ at term 144: a(144)=3 and A087802(144)=2. This sequence and A064372 first differ at term 64: a(64)=1 and A064372(64)=2. The next difference doesn't appear until a(144)=3 and A064372(144)=2. - Rick L. Shepherd (rshepherd2(AT)hotmail.com), Mar 07 2004`
