Dear SeqFans,

Considering sequence A067128:
"Ramanujan's largely composite numbers, 
defined to be n such that d(n) >= d(k)
for k = 1 to n-1",
I submitted A272879:
"If A067128(n+1) - A067128(n) is in A067128, 
then a(n) is its position in A067128, otherwise
Using table, by handy I calculated 72 terms
and found only a(47)=0. I wonder, what are
the following zero terms?

Best regards,
