%N Number of available orbitals at increasing subshells in multi-electron atoms.
%C Follows electron configuration in a multi-electron atom, which is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. Each s subshell holds 1 orbital, each p holds 3 orbitals, each d holds 5 orbitals, and each f holds 7 orbitals.
%C Theoretically, the integers follow the pattern infinitely, but (conjecturally) the subshells stop after 7p, with 8s not existing as predicted.
