SubstituteSymmetric[expr, aListOfRules, (optional On)]

Aliases: SubSym

Description: When a rule specifies that $a \rightarrow b$, then SubSym also makes the replacement $tp[a] \rightarrow tp[b].$

Arguments: $expr$ is an algebraic expression. $aListOfRules$ is a single rule or list of rules specifying the substitution to be made. On = save rules to Rules.temp, temporarily over-rides SaveRules[Off]. 'Off' can not over-ride SaveRules[On].
