%N Integers i such that 9*i = 25 X i, but 17*i is not 49 X i.
%C Here * stands for ordinary multiplication and X means carryless (GF(2)[X]) multiplication (A048720).
%H <a href="/index/Con#CongruCrossDomain">Index entries for sequences defined by congruent products between domains N and GF(2)[X]</a>
%Y Cf. Setwise difference of A115801 and A115809. A115812 shows this sequence in binary.
