  Finite geometry is employed to underpin operators in finite, d, dimensional
Hilbert space. The central role of mutual unbiased bases (MUB) states
projectors is exhibited. Interrelation among operators in Hilbert space,
revealed through their (finite) dual affine plane geometry (DAPG) underpinning
is studied. Transcription to (finite) affine plane geometry (APG) is given and
utilized for their interpretation.
