COMMENT

This is to A083815 as A097393 is to A000040. A subsequence of A014613.

FORMULA

a(n) = n-th emirpimes not used so far * R(n-th emirpimes not used so far). {a(n)} = {A097393(n)*A004086(A097393(n)))}.

EXAMPLE

a(1) = 15*51. a(2) = 26*62. a(3) = 39*93. a(4) is not 51*15 because that has already occurred as a(1). a(4) = 58*85.

CROSSREFS

Cf. A000040, A001358, A004086, A014613, A083815, A097393.
