Emmanuel asks if we know that A071196(n) exists.  As far as I know, the
answer is no. The same question applies to all of A071194, -95, etc.,
Unless someone knows of a proof (Charles Greathouse, perhaps?), I will add
an escape clause (as usual by defining the value to be -1 if ... does not
exist)

Best regards
Neil
