Information on number of saturated fusion systems

FACTS TO CHECK AGAINST FOR FUSION SYSTEMS:
For an abelian group of prime power order: identity functor controls strong fusion for saturated fusion system on abelian group|classification of saturated fusion systems on abelian group of prime power order

Group GAP ID second part Hall-Senior number Nilpotency class Number of saturated fusion systems (strict counting) Number of saturated fusion systems up to isomorphism Is the group resistant? In other words, does the identity functor control strong fusion in every saturated fusion system? (Yes if abelian) Is it a group of prime power order with no exotic fusion system?
cyclic group:Z8 1 3 1 1 1 Yes Yes
direct product of Z4 and Z2 2 2 1 1 1 Yes Yes
dihedral group:D8 3 4 2 4 3 No Yes
quaternion group 4 5 2 2 2 Yes Yes
elementary abelian group:E8 5 1 1 45 4 Yes Yes
