Comments

Sequence A071866 gives the number of terms in the n-th continued fraction.

If n is in A029707, row n is [1, (prime(n)-1)/2, 2]. - Robert Israel, May 29 2018

Robert Israel, Table of n, a(n) for n = 1..10003 (rows 1 to 2533, flattened)

Example

Prime(4)/prime(3) = 7/5 = 1+ 1/(2+1/2), so the terms associated with the 3rd continued fraction are 1, 2, 2.

Maple
