Abstract
We present a general formula for a triple product involving four real numbers. As a particular case, we get the sum of a triple product of four odd integers. Some interesting results are recovered. We derive a general formula for more than four odd numbers.
†This note is an answer to the following question: How I can calculate an infinite sum involving a triple product of four odd numbers?
