double-u

Double-u (written "u-u" or "u,u") is the sobriquet of "united under", as from 'united under Egglepple'. We use "double-u" when referencing fibor comprising so-called u-u economics (hyper/hypo). (see twistor)
UUe
The (u-u) [twistor] is connoted from the notion of recto/verso (reading frames). Each leaf/nut (u) assumes either a half-integer or integer value in twistorspace, where spacetime complexity is symmetrical and dyadic (u,u).

We may, as we see fit, take that twistorspace bundles both loopy quanta and their stringy counterparts into so-called loopstring.
