 OFFSET 1,1 COMMENTS Semiprimes that are the smallest integers m == p_i (mod p_(i+1)), i=1..n; p_i = i-th prime, for some n's.. Note that these are not the smallest semiprimes m == p_i (mod p_(i+1)), i=1..n. Instead for n=9,13,17,18,20,22,41, a(n) is the smallest semiprime for the given n. LINKS Table of n, a(n) for n=1..7.
