I found some related questions that came up in these days from the user Ali Sadegh Daghighi. It is about the combinatorial meaning of tetration...
[MSE]What combinatorial quantity the tetration of two natural numbers represents?
Another interesting related question is the following.
[MSE]Are there non-equivalent cardinal arithmetics?
At the end here there is another sequence of operations over the cardinals: seems the low-Hyperoperations sequence.
[MSE]How large is an uncountable regular cardinal which is closed under arbitrary fast operators?

Mother Law \(\sigma^+\circ 0=\sigma \circ \sigma^+ \)
\({\rm Grp}_{\rm pt} ({\rm RK}J,G)\cong \mathbb N{\rm Set}_{\rm pt} (J, \Sigma^G)\)
