C888 — Join the NT lattice to the general Key domain theorem

Question

Finding

The NT return rule is the h=70 instance of the general theorem. E/P returns remain0,23,46,69 and0,69; J has only the fixed hinge in this finite domain. Integer output and return to a named slot are different requirements, even when these particular finite index sets coincide.

Reassessment

Integrate the operator results as grid and anchor registers.
