Oops, should have said <REMOVE> (projection) and <RENAME> are always
fundamental.

I am sorry to be so dense, but I need further explanation...

I asked whether <AND> <OR> &<NOT> are the three fundamental ones you
referred to.

I sounds, from your two answers as though the answer is "no". If I
understand you right, the three fundamentals are:

Either <NAND> or <NOR>, take you pick.
<REMOVE> (projection)
&
<RENAME>

Is this right?
