Two related questions: Are the seven independent axes (dimensions) of the octonian space relatable to the adult capacity of STM (short term memory – number of independent objects simultaneously retainable in the mind)?
Can octonions serve as a mathematical Rosetta stone for cognitive and brain modeling by linking the world of algebra (operators, e.g. for mental rotation) to the world of geometry (relations, membership, and clustering), by exploiting the fact that octonions are composed of algebraic structures (7 quaternion sets) that also map onto a simple projective geometry structure (the Fano plane) that is organized as a system of 7 lines and 7 points?
