how to incorporate higher symmetry point groups?

how to incorporate higher symmetry point groups like 'Cinfinity,v' and 'Dinfinity,h' in 'define' for obtaining exact degeneracies in the molecular orbitals?

Hello,

it is not possible to use C_infinity (for a linear molecule, I guess), C99 is the maximum one can set. But you have a finite number of orbitals, so to obtain exact degeneracies a point group which covers the number of orbitals within one irrep should be sufficient, I guess.
