COMMENT
|
See A048888 for the definition of OR-numbral arithmetic.
This sequence is not multiplicative; for example a(15) = 127 != 7 * 21 = a(3) * a(5). It is totally OR-numbral multiplicative: a([n] * [m]) = [a(n)] * [a(m)] in OR-numbral arithmetic. - Franklin T. Adams-Watters (FrankTAW(AT)Netscape.net), Oct 27 2006
