Penetration modifier

This is mentioned in Basic Set: Characters in several places:
*102: Armor Divisor is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Contact Agent (p. 103) and Follow-Up (p. 105).
*103 (Cosmic, irresistible attack) You cannot combine this enhancement with other “penetration modifiers,” such as Follow-Up (p. 105).
*103 (Cyclic) All penetration modifiers (e.g., Contact or Follow-Up) continue to apply;
*105 Follow-Up is a “penetration modifier”; you cannot combine it with other penetration modifiers (although the carrier attack can have them).
*106 Malediction is a “penetration modifier”; you cannot combine it with other penetration modifiers
*108 Respiratory Agent is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Follow-Up (p. 105).
*109 Sense-Based is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Follow-Up (p. 105).
*109 (Side Effect) you cannot combine it with penetration modifiers other than Armor Divisor
*110 Armor Divisor is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Contact Agent (p. 103) and Follow-Up (p. 105).
*111 (Blood Agent) This is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Follow-Up (p. 105).
*111 (Contact Agent) This is a “penetration modifier”; you cannot combine it with other penetration modifiers, such as Follow-Up (p. 105).
*332: Penetration modifiers, 378, 416; overpenetration, 379, 408.
*417: has overview
Based on these, the eight modifiers which are explicitly penetration modifiers include:
#Armor Divisor
#Blood Agent
#Contact Agent (ie Contact)
#Follow-Up
#Irresistible Attack
#Malediction
#Respiratory Agent
#Sense-Based (unless as a limitation on Malediction, only illegal as enhancement)
All of them specify they cannot be combined with other penetration modifiers. They give examples "such as" but are not limited to them.
Presumably anything besides these 8 are not classified.
