Is the base 2 version in the EIS? I have not checked. What about this sequence with other bases (3,4,5,6, etc)?
In general, I suggest, someone should add all the base-2 missing 'base' sequences that already exist in the database as base 10 versions (submitted by Eric Angelini and others), and submit base 10 versions of 'base' sequences that involve base 2 (submitted by me and others).
And of course, someone could calculate and submit the base 3, base 4, base 5, etc versions of both the base 10 and the base 2 sequences, if these sequences do not already exist in the database.
:)
Thanks,
Leroy Quet
