Palindromic polynomial

From Wikipedia, the free encyclopedia

A polynomial is palindromic, if the sequence of its coefficients are a palindrome.

Ie, let P(x) = \sum_{i=0}^n a_ix^i be a polynomial of degree n.

P is palindromic if ai = ani for i=0...n.

Similarly, P is called antipalindromic if ai = − ani for i=0...n.

See also: Reciprocal polynomial, for the complex conjugated version.
