Rational numbers with palindromic repeat periods of length n are palindromic every n digits; The Thue-Morse constant (in binary) is palindromic at powers of 4 digits. What other sequences of palindromic truncation lengths are possible? On Mon, Nov 23, 2015 at 7:13 PM, Dan Asimov <asimov@msri.org> wrote:
Clearly.

In the decimal approximation case, you get a palindrome if you truncate after three terms. In the cf you get one if you truncate after *any number* of terms!

In what sense? There is no orientation-reversing map of the sequence of C.F. integers to itself that maps each integer to itself.

But why stop with 161; cf(phi) is also a palindrome.
