- order, product of chains, ideal of maximum height, and digit sum sequence
- Language:
- English
- Description:
- We maximize the total height of order ideals in direct products of finitely many finite chains. We also consider several order ideals simultaneously. As a corollary, a shifting property of some integer sequences, including digit sum sequences, is derived.
