a hard sequence worthy of attention

[N. J. A. Sloane]

J.A. said:
just to check, do you mean the 2^n boolean functions
that are linear over B = GF(2), i.e., viewing B^n as
a finite dimensional vector space, their number is
equal to |B^n|?

Me:  I am talking about the 2^2^n Boolean functions
of n variables, counting them mod addition of
linear functions together with all the
usual symmetries.
