Odd rational palindrome quotient conjecture

About 4 years old · traced to

Let p>1p>1 be odd. A rational number p/qp/q has a palindromic quotient representation if there are palindromic numbers AA and BB such that p/q=A/Bp/q=A/B. Odd rational palindrome quotient conjecture. For every odd number p>1p>1 with p≠23p\ne 23, there exists an odd number q<pq<p such that p/q=A/Bp/q=A/B has a solution in palindromes A,BA,B.

The conjecture is based on the paper’s automaton construction and computational study of rational solutions; the source does not state a proof or resolution.
