There are infinitely many elliptic Carmichael numbers

In 1987, Dan Gordon defined an elliptic curve analogue to Carmichael numbers known as elliptic Carmichael numbers. In this paper, we prove that there are infinitely many elliptic Carmichael numbers. In doing so, we resolve in the affirmative the question of whether there exist infinitely many Lucas-Carmichael numbers (that is, squarefree, composite integers n such that for every prime p that divides n, p+1|n+1) .
