But you have to realise that Bird uses ordinals to "index" his structures, not the numbers those structures result in. The algorithmic reduction of expressions is important too.

The upload rule is most characteristic of both Bowers and Bird. The size, depth, etc. of higher structures is increased from the 2nd entry, that explodes the whole expression. Hence "Bowers Exploding Array Notation" (BEAN).
