irregular primes l with 2000< l < 2521

In Vandiver, H. S. “Examination of Methods of Attack on the Second Case of Fermat’s Last Theorem“, P.N.A.S. 1954 (vol 40), Vandiver found by computation that there are 26 irregular primes p such that 2000 < p < 2521.

Computations I did with PARI/gp show the same.  Below, `l’ and `2a’ are as in Vandiver’s 1954 paper referenced above.
