%N Integers i such that 15*i = 27 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. Subset of A048719 ? Differs from A048719 for the first time at n=8, where A048719(8)=99, while a(8)=102. (Note: 99 = 1100011 in binary). A115808 shows this sequence in binary.
