COMMENTS
The initial terms coincide with those of A170751, although the two sequences are eventually different.
First disagreement at index 17: a(17) = 23277539895909928442510896, A170751(17) = 23277539895909928442511392. - Klaus Brockhaus, Mar 28 2011
Computed with MAGMA using commands similar to those used to compute A154638.
