COMMENTS
The initial terms coincide with those of A170760, although the two sequences are eventually different.
First disagreement at index 24: a(24) = 288511851128422399999999999999999999180, A170760(24) = 288511851128422400000000000000000000000. - Klaus Brockhaus, Apr 20 2011
Computed with MAGMA using commands similar to those used to compute A154638.
