A233360 Primes of the form L(k) + q(m) with k > 0 and m > 0, where L(k) is the k-th Lucas number (A000204), and q(.) is the strict partition function (A000009). 4

COMMENTS

Conjecture: The sequence has infinitely many terms.

This follows from the conjecture in A233359.

EXAMPLE

a(1) = 2 since L(1) + q(1) = 1 + 1 = 2.

a(2) = 3 since L(1) + q(3) = 1 + 2 = 3.

a(3) = 5 since L(2) + q(3) = 3 + 2 = 5.
