This comment is about the four sequences A001034, A060793, A056866, A056868: The Feit-Thompson theorem says that a finite group with odd order is solvable, hence apart from the first trivial term of A060793 all the other numbers in these sequences are even. - Ahmed Fares (ahmedfares(AT)my-deja.com), May 08 2001
