Create a New Array from a Different Array

[DoubleA70]

Hello,
I have an array of 1048320 rows (let's call it P) and I need to do the following operations (I have tried a few things but my MathCAD knowledge is rusty)

I need to create a new array with 720 rows (let's call it Q). The first row in Q will be the summation of rows 0,720,1440... from P. The second row in Q will be the summation of rows 1,721,1441... from P. And so on for all 720 rows in Q.

Like I said, my MathCAD knowledge is pretty rusty so I wasn't able to figure out a program. If anyone can lend some advice it would be GREATLY appreciated. Thanks!!

No programming needed, just a formula.

n:1;720
P[n:Q[...+Q[...+

Thanks for the reply, but could you be a little more specific? I attached my attempt at it.

@DoubleA70: Before I get into this (work involved), why would anybody want to do this?

There's always homework, isn't there?
