 OFFSET 1,1 COMMENTS Conjecture 1: The union of this sequence and A282793 is A153815. Conjecture 2: The zeta zeros whose indices are terms of this sequence are the locations where the zeta zero counting function, (RiemannSiegelTheta(t) + Im(log(zeta(1/2 + i*t))))/Pi + 1, undercounts the zeta zeros on the critical line. Conjecture 3: This sequence consists of the numbers k such that sign(Im(zetazero(k)) - 2*Pi*e*exp(LambertW((k - 15/8)/e))) = -1. Verified for the first 100000 zeta zeros.
