Talk:Frobenius numbers
(Redirected from Talk:Frobenius primes)
title of this task[edit]
These are not Frobenius primes. Indeed, some numbers of this series aren't prime.
According to OEIS, they are known as the Frobenius number of the numerical semi-group generated by prime(n) and prime(n+1) (as noted in the OEIS entry A037165 by Victoria A. Sapko). They are also known as Frobenius numbers. -- Gerard Schildberger (talk) 22:57, 1 April 2021 (UTC)

task clarification[edit]
It appears that when the task's author stated:
a(n) = prime(n)*prime(n+1) - prime(n) - prime(n+1), where prime(n) < 10,000
it was meant to mean:
a(n) = prime(n)*prime(n+1) - prime(n) - prime(n+1), where a(n) < 10,000
This is based on the output for the Ring example's output. -- Gerard Schildberger (talk) 23:33, 1 April 2021 (UTC)
task wording[edit]
I think that the task description would read better with:
FrobeniusNumber(n) = prime(n)*prime(n+1) - prime(n) - prime(n+1), where FrobeniusNumber(n) < 10,000
instead of using a(n). -- Gerard Schildberger (talk) 23:48, 1 April 2021 (UTC)
