This sequence (like A100323 relative to A100322) is not necessarily a subset of A100332 because there may exist an n1<n such that the decimal places of both exp(n1) and exp(n) begin with n. Then n appears in this sequence, but n1 appears in A100332.
Table of n, a(n) for n=1..4.
Cf. A100323 for analogous sequence relating to powers of Pi.
