EXAMPLE

In the following examples, X stands for the carryless multiplication of GF(2)[X] polynomials (A048720):
41 is a member for the same reason.
123 is a member, because 123 = 3*41, thus A235041(123) = A235041(3) X A235041(41) = 3 X 41 = A048720(3,41) = 123. That is, we happen to get the same result back as 3, '11' in binary, and 41, '101001' in binary, can be multiplied together to 123, '1111011' in binary, without producing any carries.


PROG

(Scheme, with Antti Karttunen's IntSeqlibrary, two alternative definitions)
(define A235045v2 (FIXEDPOINTS 1 0 A235042))


CROSSREFS

The sequence differs from its subsequence A235032 for the first time at n=54, where a(54)=135, while A235032(54)=137.
