Yes, it is discussed somewhere: https://tex.stackexchange.com/q/372326/121799. @azetina Too bad, you are calling for egreg and get David instead. ;-) – May 30 '19 at 02:41

1I'd say not "star times star" but "star convoluted with star". – Sergei Golovan May 30 '19 at 04:42

@SergeiGolovan actually I was just reading a paper where the main function constructed is called $*$ (but it is never convoluted with itself) – Bjørn Kjos-Hanssen May 30 '19 at 05:20
