A few more unproven: A065083, A090315, A104885, A121091.

Also, a couple I'm not sure of:

A051346: Numbers n that can be written as n = k/d(k) in four or more 
ways (may be incomplete).  From David W. Wilson; perhaps he can tell us 
what this note means.

A115016 Smallest number k that has a shortest addition chain whose 
length A003313(k) = A003313(n*k), 0 if this never happens.  With the 
comment: It is conjectured that no shortest addition chains exist such 
that A003313(m)=A003313(m*2^k) for k>1.  This leaves me unsure whether 
the 0's in the table for 4 and 8 are known or conjectured.
