title of this task
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)
- Thanks. I've gone ahead and moved the page to
Frobenius numbers
. --Chunes (talk) 05:25, 2 April 2021 (UTC)- However, it appears that Frobenius numbers are quite a bit more general than this. This sequence is the Frobenius numbers for a very specific input. --Chunes (talk) 05:35, 2 April 2021 (UTC)
task clarification
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
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)
