| Jul 18, 2016 at 21:09 | comment | added | Robert Israel | These are the partial sums of OEIS sequence A046080; there is a formula there for $A046080(n)$ in terms of the prime factors of $n$. A "closed-form" formula for $A224921(n)$ would seem unlikely. | |
| Jul 18, 2016 at 18:48 | comment | added | Yemon Choi | @StevenLandsburg In my interpretation, no. One wants all elements of the triple to lie strictly between the two limits | |
| Jul 18, 2016 at 17:54 | comment | added | Steven Landsburg | @YemonChoi: If the reply to Gerry's question was clear, then (without looking at the edited version of the question) how many Pythagorean triplets are there between 7 and 11? Is $(6,8,10)$ between 7 and 11? | |

| Jul 17, 2016 at 11:10 | comment | added | Mathivanan Palraj | for example, between 2 and 6, there is one Pythagorean triplet, namely, 3, 4, and 5. Also between 2 and 6, there is only one triplet. However, between 2 and 11, there are two triplets: (3,4,5), (6,8,10). | |
| Jul 17, 2016 at 9:58 | comment | added | Gerry Myerson | What does it mean for a triplet to be between two integers? Do you want the hypotenuse to be between the two integers? There is a tabulation at oeis.org/A224921 | |
