Dear John,
Accessing rows (which evaluates the character values) is just by calling :
gap> c := CharacterTable("L2(7)");
gap> Irr(c);
I am not sure how to access columns. You can check what are the available
options
for the stored data "c" (= the character table) by calling
gap> KnownAttributesOfObject(c);
[ "Size", "NrConjugacyClasses", "Irr", "OrdersClassRepresentatives",
"SizesCentralizers", "AutomorphismsOfTable", "UnderlyingCharacteristic",
"ClassNames", "Identifier", "InfoText", "ComputedPowerMaps",
"ComputedClassFusions", "NamesOfFusionSources", "CASInfo", "FusionToTom",
"ProjectivesInfo", "ExtensionInfoCharacterTable" ]
best,
Siddhartha
