%I #6 Mar 31 2012 13:21:10

%N Integers i such that 9*i = 25 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 Seems to be a superset of A115809. A115811 gives the terms not present in A115809. A115802 shows this sequence in binary.
