RuleFiringAt(AngouriMath.Entity)

Method (no overloads)

Summary

The rule that fires at this node, or null where none does.

Remarks

At this node only, leaving its children alone — which is what an arm of the
switch sees. Always null for a set with no Rules.
Firing means changing the node. An arm can match and then decline: the factorial
arms match any quotient of factorials and hand back what they were given where the two
offsets are a hundred apart, since writing that product out is not a simplification.
Naming such an arm here would report a rewrite that did not happen, so a rule that
returns the node it was given is not the rule that fired.
