Cheers,
I would like to create an index entries for these two kinds of sequences:
(because I'm submitting a lot more of them soon...)

How should I refer to these kind of sequences?
Should the first be called "Congruent Products" or "Congruent product
identities"
or "Sequences defined by Congruent Products under XOR" ?
Or are we stretching the term "congruent" here a bit?
How about "XOR-congruent multiplicative/product identities"?
and should the second kind be called say "Cross-domain multiplicative identities"
or "Cross-domain product identities" ?
(E.g. as the is an ordinary multiplication * (of ring N) used at the right side
and the carryless multiplication A048720 (which makes its most natural sense in the GF(2)[X] polynomial ring)
at the right side.)
Or something else?
Yours,
