%C 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 all numbers in this sequence are even. - Ahmed Fares (ahmedfares(AT)my-deja.com), May 08 2001

%C The primitive elements are A257146. These are also the primitive elements of A056866. - _Charles R Greathouse IV_, Jan 19 2017
