%N A092861 "Product" of the sequence of primes and the "evil" numbers (A001969).
%C A092861 If two monotonic sequences are mapped into the real section of (0,1), as it is defined in A051006 and the product of the two reals mapped back into the set of monotonic sequences as defined in A092855, then we have the "product" of the two sequences.
