This program performs calculations of the type described by J. A. Pople and G. A. Segal (see QCPE 91). This program was developed from the Extended Hckel scheme of R. Hoffmann (QCPE 48) and so should be somewhat familiar to users of the latter routine. Facilities are provided for treating first- and second- row atoms, with up to 42 atomic orbitals.
