FORMULA
{A004086(A158126(i)) such that A004086(A158126(i)) is an element of A000040}.
EXAMPLE
a(1) = 2161 because this is prime, and R(A158126(2)) = R(1612) = 2161. a(2) = 39841 because this is prime, and R(A158126(20)) = R(148930) = 039841 which in OEIS form strips away leading zero to become 39841. a(7)is the prime 854431 = R(A158126(16)) = R(134458).
