Could the sequence A287326 be generalized in order to receive expansion of natural power n>3?

The sequence https://oeis.org/A287326 - is Binomial distributed triangular array, that shows us necessary items to expand perfect cube n3n^3. Summation of nn-th row of Triangle A287326 from 00 to n1n-1 returns n3n^3. But is it exist simillar patterns in order to receive expansion of power n>3n>3, where nn - positive integer?

     Figure 1. Triangle A287326.

It derived by means of identity

x3=m=0x13!mx3!m2+1 x^3=\sum\limits_{m=0}^{x-1}3!\cdot mx-3!\cdot m^2+1

For detailed info on derivation, please, reffer to links below. Thank you !

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
