COMMENTS
The initial terms coincide with those of A170766, although the two sequences are eventually different.
First disagreement at index 17: a(17) = 18889617541497286590540479431, A170766(17) = 18889617541497286590540480512. - Klaus Brockhaus, Mar 28 2011
Computed with MAGMA using commands similar to those used to compute A154638.
