Extract

Junior School children seem to be able to get the feel of the Klein group by using aptly-prepared paper sheets and wooden blocks. Perhaps, surprisingly, they can also handle such logical implications (when suitably embodied in devices) as:

A→B, ∼B→∼A, B→A, and ∼A→∼B

Here “→” means “implies” and “∼” means “not.”
