Nalewajski has developed and presented a complete theory of chemical reactivity derived from DFT and from the information theory. 5,36 However, hyperhardness, the global energy derivative of the third order over the number of electrons 𝛾 = [𝜕𝜂/𝜕𝑁] 𝑣 and other third energy derivatives, have rarely attracted attention in cDFT. The first attempt for calculation 𝛾 has been provided by Fuentealba and Parr. Ordon and Tachibana have published original approach to obtaining 𝛾 with the use of the nuclear reactivity indices and the Maximum Hardness Principle. Later, another in-depth analysis of the local energy derivatives of higher orders has been presented in the work by Cardenas et al and the systematic and explicit approach to the whole body of cDFT energy derivatives was presented by Heidar-Zadeh et al. However, no attempt to tracing a general way to their numerical values has been indicated. The widely recognized derivative proposed by Morell 𝑓
