   The density of the fcc-C22 crystal reported in the text was wrong. The sentence on p. 573,
10th line from the bottom, reporting on the density of the fcc-C22 crystal and reading:

    “The density is 1.78 g/cm3 , close to that of fullerite (1.68 g/cm3 ), but the bulk modulus
is as large as 239 GPa due to the presence of covalent interlinks between adjacent C20 cages.”

must be corrected as

    “The density is 2.75 g/cm3 and the bulk modulus is as large as 239 GPa due to the presence
of covalent interlinks between adjacent C20 cages.”
