[GAP Forum] SmallGroup Library not founded

[Daniel Dupard]

  Dear GAP forum,

Working on a function to test isomorphism of non polycyclic groups and 
testing it on all SmallLibrary groups, I sometimes receive this sort of 
message (see below)

For your information, I checked that I had id480.z file in /small/id2/ 
directory and sml480.z file in /small/small2/ directory both being readable

Does anyone have any idea of what can I do to solve my problem ?

Best wishes,
Daniel Dupard
