Which point sets realize a given distance multiset? Interesting cases include the “turnpike problem” where the points lie on a line, the “beltway problem” where the points lie on a loop, and… (More)

We consider the problem of determining which point sets in some given space realise a given distance multiset. Special cases include the “turnpike problem” where the points lie on a line, and the… (More)

We study the number of ways to factor a natural number n into an ordered product of integers, each factor greater than one, denoted by H (n). This counting function from number theory was shown by… (More)
