%N Numbers n for which A234742(n) = n: numbers n whose binary representation encodes a GF(2)[X]-polynomial such that when its irreducible factors are multiplied together as ordinary integers (with carry-bits), the result is n.

%o (define A235035 (MATCHING-POS 1 0 (lambda (n) (or (zero? n) (= n (reduce * 1 (GF2Xfactor n)))))))
%Y Gives the positions of zeros in A236379, i.e., n such that A234742(n) = n.
%Y An intersection with A235034 gives A235032. Contains A014580 as a subsequence.
%Y Cf. A235036, A235032-A235033, A234742.
