Michel Marcus: I don' t see why A257309 has name hyper-4, for instance in the examples where does the 4 appear

Natan Arie' Consigli: The sequence A257309 is about hyper-4 powers which are numbers that could be written as a^^b in caret notation or as a[4]b in the equivalent box notation.
In general a^[x]b = a[x+2]b.
