Re primitive binary matrices?

[N. J. A. Sloane]

1.  Thanks to kennedy at oldnews.org and wouter.meeussen at vandemoortele.com
for computing the start of that sequence - it will be A070322
in a few minutes

2.  Yuval Dekel <dekelyuval at hotmail.com> asks if these two
sequences are in the OEIS:

Symmetric invertible 0,1 matrices (over the reals)
Symmetric invertible 0,1 matrices (over GF(2))

I don't know the answer - could someone work
out a few terms and check?
