You beat me to the punch.   I was going to enter a Rosetta Code problem next week which would've been called the Frobenius problem or some such   (I'm currently working on the wording of an unrelated Rosetta Code task).

 The function   Frobenius(a list of some numbers)     returns the largest number for the Frobenius equation:
                       I1*x1  +  ...  +  In*Xn   =   B.   
 At least two integers should be supplied.  If the integers aren't relatively prime,
 the result is infinity and is indicated by a negative one (-1) which is returned.  
 If any of the integers is equal to  1  (unity),  then  0  (zero) is returned.     
 Another way of approaching the description of the Frobenius number is:   given a set of integer-demoniation
 stamps (say,      and   ),  what is the largest value that those stamps can't represent?

This is why this problem is also known as the postage-stamp problem and was a real problem when buying stamps for mailing a package at the post-office which may have a restricted set of stamps, and people wanted/collected the different stamps, not wanting 41 one-cent stamps put on a package or envelope.   (Now-a-days, of course, the post office just produces a digital imprint of the exact decimal postage amount.)

I would have added some sets of numbers that have no highest value,   as well as "stamps" that are multiples of another.

I would not have restricted the high limit to   100,   but left that open-ended   (in other words, infinity).

It would also get around the use of a trade-marked (TM) term(s) and also a registered (R) trade-mark term, but it seems that Wikipedia skipped around those problems.   &bsp; -- Gerard Schildberger (talk) 21:35, 25 October 2018 (UTC)
